Abstract
The appearance of magnetic anisotropy has been established by magnetometric methods in the amorphous Fe76Si13B11 ribbon after pulsed laser heating in an external magnetic field. Effects of laser heating on the physical properties of the alloy, in particular, on the Curie temperature and the temperature of crystallization, have been investigated. It is shown that the value of the remanence of the alloy samples after such treatments in a longitudinal magnetic field increases by a factor of more than three. There is suggested a mechanism of the appearance of a uniaxial magnetic anisotropy of amorphous ribbons during the pulsed laser heating in a magnetic field under conditions that do not lead to the crystallization of the alloy.
