In July, 2021, 5 students from the National University of Science and Technology “MISIS” have had one week’s practical training at the REC “SMBA”.

Alina Tatarova has learned the techniques of differential scanning calorimetry and has learned to investigate phase transitions in microwires and the Curie temperature using indirect methods. Alyona learned how to measure the temperature gradient during the current annealing of microwires with an infrared thermal imager. Ksenia Ivanova studied the effects of microwire composition and tensile stress on its magnetostriction. Tatiana Blokhina investigated the optical properties of nanoparticles for biomedical applications. Anastasia Masterihina synthesized polymer nanocomposites and studied their micromagnetic properties by atomic force microscopy.

At the end of the internship, the girls held a workshop for the REC staff to present the results of their work.

It has been a fruitful working week and we wish the girls further success in their studies!

2 August, 2021

Since July 12, our three bachelor students undergo an internship at the Saratov State University in the Magnetic metamaterials laboratory under the leadership of Dr. Alexander Sadovnikov.  Zoja Grigorieva has done the project on stray fields modeling of ferromagnetic nanoparticles using Comsol Multiphysics. Mikhail Aronov was working on the creation of a digital model of a smart composite based on a thermosensitive polymer. Vitalii Salnikov is working on modeling of exchange bias multilayers by using the Mumax software. These projects are related to their investigations in the REC “Smart materials and biomedical applications”. The students also got acquainted with the unique Brillouin spectroscopy device, which allows direct registration of spin waves and oscillations in magnetic micro-and nanostructures, with high spatial, temporal, and spectral resolution. We wish the guys to get interesting results and enjoy the process!

The last year our postdoc Christina Gritsenko won a one year postdoctoral research position for the 2021 year at the Pavol Jozef Šafárik University in Košice (https://www.upjs.sk/prirodovedecka-fakulta/). She proposed a scientific project aimed with the magnetooptical investigations of 1D and 2D magnetoplasmonic crystals based on Permalloy. These studies are of a shared scientific interest of our Research and Scientific Center and the Nanotechnology Laboratory, led by Mgr. Vladimír Komanický, Ph.D.

In January-February and May-June Christina visited the University in Kosice to fabricate the first series of 2D magnetoplasmonic crystal samples by the electron beam lithography method.

In April 2021 the new experimental equipment arrived at the REC “SM&BA” – the scanning probe microscope NTEGRA, supplied by NT-MDT (Russia) (web-site: https://ntmdt-russia.com/). Our new microscope possesses wide scope of functions: atomic/magnetic/piezoelectric force microscopy, tunneling microscopy, nano-lithography, mapping of Young modulus, mechanical stiffness and adhesion. NTEGRA also provides the possibility to perform scanning in liquids which is extremely helpful when working with living cells. All the REC “SM&BA” researchers are inspired by the opportunity to study their functional novel materials (elastic composites, microwires, thin films, two-dimensional MXenes, cell cultures) with the new setup. Sergey Mitko, the engineer of NT-MDT, visited REC “SM&BA” laboratory in STP “Fabrika” for a week to teach our crew how to operate with the new device. The training was undoubtedly helpful, almost all the researches of REC “SM&BA” have participated in it and learned the important insights concerning their own samples investigation.

How to improve the magnetoelectric properties of polymer nanocomposites?

In a study by LNMM members, together with colleagues from the University of Genova (Genova, Italy), Uppsala University (Uppsala, Sweden) and the National University of Science and Technology MISiS (Moscow, Russia), two strategies are presented to improve these properties. In the first case, clusters of magnetic particles were distributed and oriented in a polymer matrix using an external magnetic field. In the second case, the improvement of the magnetoelectric properties was achieved by incorporating piezoelectric particles into the polymer matrix.
Detailed information can be found in the article.

Today we are pleased to announce that the submission of papers to Special Issue on “Magnetochemistry” is open. This Special Issue aims to provide a valuable forum for scientists to share their new findings related to both fundamental and applied research on magnetic hysteresis, which is a key property of all ferromagnetic materials. In this issue, special attention will be paid to two scientific problems. The first is predicting the behavior of a magnetic system during magnetization reversal, taking into account the known parameters of the system. Here, the most important topics are the fundamental theory of ferromagnetism and the modeling of hysteresis processes. The second is the determination of intrinsic properties of materials based on the observed magnetic hysteresis. On this basis, the topics to be covered can include but are not limited to:

1. Theory and modeling of magnetic hysteresis

  • Ab initio theory of ferromagnetism, exchange interaction;
  • Brown and related equations, statement of problem and solutions;
  • Hysteresis curve modeling and calculation;
  • Magnetization dynamics modeling;
  • Novel methodic of precise hysteresis investigations;
  • FORC analysis for magnetic systems.
2. Magnetic hysteresis versus material composition and properties

Our PhD student Sobolev Kirill visited National University of Science and Technology “MISiS” (Moscow, Russia) to work on his current Mobility grant, provided by the Russian Foundation of Basic Research. The grant was won under supervision of Dr. Mikhail Gorshenkov, so, all the researches were conducted in collaboration with him. Kirill learned the perspective techniques to chemically purify MAX-phase samples and finalized the experimental protocol of phase-pure synthesis of these materials. In addition, an attempt was made to hot-press the prepared pure powders to dense tablets that can be further used as sputtering targets for thin film synthesis.

Magnetocrystalline and surface anisotropy in nanoparticles:

Members of LNMM together with colleagues from Italy and Spain released research devoted to the investigation of magnetic properties of ultrasmall magnetic nanoparticles. In such small magnetic nanoparticles, the surface anisotropy, internal cation distribution and spin canting drastically affect the magnetic properties. 

In the presented study, we investigate how magnetic properties of cobalt ferrite evolve with the increase of size from 2.5 to 7 nm controlled by thermal annealing, and how thermal annealing affects those properties of the smallest particles. 

More info you can find in the artircle.

Nanoparticles matters in cancer treatment

Research of LNMM scientists and their collaborators reveals the secrets of autophagy and apoptosis in human cancer cells.
The wide research performed with Institute of Physics of the Czech Academy of Sciences (Prague, Czech Republic), Institute for Clinical & Experimental Medicine (IKEM, Prague, Czech Republic) and National University of Science and Technology “MISIS” (Moscow, Russia) describes details of intracellular cell death processes induced by iron oxide nanocubes and nanoclusters.
The results indicate that the cytotoxic effects of iron oxide nanoparticles require more intensive study and that they should be considered in biomedical applications, particularly in patients with liver diseases.

This prospect of development of cancer treatment became possible in virtue of 5-100 project mobility program.
