Abstract

A study is performed of rapidly quenched alloys of the Finemet type with different compositions. The Curie temperature, Bloch constant, critical exponent, and spontaneous magnetization at 0 K are calculated by analyzing the low- and high-temperature dependences of magnetization. A linear correlation is found between the constant of spin-wave stiffness and the Curie temperature.
