INFLUENCE OF UNIAXIAL COMPRESSIVE STRESSES ON MAGNETIC-PROPERTIES ACROSS AN FE79.1CR4.3B16.6 AMORPHOUS FERROMAGNETIC RIBBON

The influence of uniaxial compressive stresses on the energy of magnet oelastic anisotropy of an amorphous ferromagnetic alloy with compositi on Fe79.1Cr4.3B16.6 has been investigated. Uniaxial pressure within a part of the sample cross-section was obtained by straightening out the ribbon annealed in a toroidal shape. The bulk value of the energy of magnetoelastic anisotropy was determined from the hysteresis loop trac ed with a fluxmeter. The energy of magnetoelastic anisotropy of surfac e layers approximately 50 nm thick was determined from hysteresis loop s traced with a hysteresigraph based on the transversal Kerr effect. T he experimentally obtained values were found to be in good agreement w ith the calculated ones.
