Effect of pulsed laser heating on the magnetic properties of amorphous alloy 30KSR

It has been established using magnetometric methods that irreversible magnetic anisotropy appears in the amorphous ribbon of a 30KSR alloy after pulsed laser heating in an external magnetic field. Effects of laser heatings on the physical properties of the alloy, in particular, on the Curie temperature and the temperature of crystallization have been studied. It has been shown that the direction of the arising magnetic anisotropy does not coincide with the field direction during laser heating. A mechanism of the appearance of the uniaxial magnetic anisotropy of amorphous ribbons during pulsed laser heatings in a magnetic field by regimes which do not lead to crystallization has been suggested.
