Study of the influence of mechanical stress (pressure) on hysteresis loops of Fe-3% Si undirected steel and thin strips. Observation of magnetic domains.
Study of magnetic domains, magnetoacoustic emission and Barkhausen noise on materials combining ferroelastic and ferromagnetic behavior - Ni-Mn-Ga.
A fast PXI card based measurement system for Barkhausen noise, acoustic emission, eddy current and reversible permeability at various frequencies and GMIs up to 100 kHz was prepared. Target - detection of magnetic properties of surface layers on steels and other magnetic materials.
A measurement system was prepared to measure the dilatation, resistivity, and ac susceptibility of samples (e.g., Ni-Mn-Ga) at different temperatures.
