Setup for measurements of local nucleation field distribution along the bistable microwires.

Setup for measuremnets oflocal nucleation field distribution along the bistable microwiresThis setup contains a very short exciting coil that induces a reverse domain nucleation that is detecting by a pick-up coil. After each measurement, a motor drive moves slightly the microwire and a next measurement is taken. In this way a distribution of local nucleation field is measured. The local nucleation fields are highly affected by the different inhomogeneities (defects) existing inside the microwires. Thus this equipment can be used for a quality control of the microwires.
