Surface microstructure and magnetic behavior in FeSiB amorphous ribbons from magneto-optical Kerr effect

Popis výsledku v původním jazyce

Surface sensitive methods, namely the magneto-optical Kerr effect (MOKE), integral lowenergy and conversion electron Mössbauer spectroscopy (ILEEMS, CEMS), and scanning and transmission electron microscopy (SEM, TEM), have been used with the aim to tracethe surface microstructure and magnetic properties of FeSiB amorphous ribbons prepared by planar flow casting. The general composition of studied samples is Fe80SixM20-x, where x = 4, 6, 8, 10 at.%. It is shown that MOKE used for magnetization, hysteresis loop, and domain structure determination is highly beneficial in a detection of both surface crystallization and local ordering of atoms into magnetically different clusters of amorphous structure. Moreover, a combination of blue and red laser with different penetration depth yields unique results concerning the surface anisotropy and depth sensitivity. In the case of samples with 4, 6, and 8 at.% Si MOKE detects two magnetically different phases diverging in coercivity values Hc howe
