Magneto Optical Kerr Effect

The Wiegand wire is known to exhibit a unique feature of fast magnetization reversal in the magnetically soft region accompanied by a large Barkhausen jump. We clarified a significant difference between the magnetization reversals at the surface and at the entire cross section of a Wiegand wire. We conducted magnetization measurements based on the magneto-optical Kerr effect and applied conventional methods to determine the magnetization curves. The switching field of the magnetization reversal at the surface was greater than that at the initiation of a large Barkhausen jump. Our analysis suggests that the outer surface layer exhibits low coercivity.

Magneto Optical Kerr Effect

Hybrid magnetic heterostructures made of epitaxial manganite La0.7Sr0.3MnO3 thin film and intermetallic superlattice (TeCo2/FeCo)n were prepared on orthorhombic NdGaO3 substrates and characterized by means of magneto-optical Kerr effect and magnetoresistance. Experimental data show that magnetic interaction between La0.7Sr0.3MnO3 and (TeCo2 /FeCo)n is of the antiferromagnetic type. The features observed in magnetotransport characteristics are caused by the magnetization reversal at the interface between manganite thin film and intermetallic superlattice.
