Abstract

The magnetization variation with a temperature of Y_xFe _80-xB₂₀ and Y_xCo_70-xB₃₀ amorphous ribbons has been investigated. For an accurate description of the low temperature behaviour of magnetic properties the spin wave theory has been used. The value of the spin wave stiffness constant, D, was calculated for all investigated samples. For the ferromagnetic Y-Co-B alloys D is a linear function of Curie temperature, T_C. An analogous relation for asperomagnetic Y-Fe-B ribbons was not found
