MAGNETIZATION OF AMORPHOUS MAGNETS

open access: yesLe Journal de Physique Colloques, 1979
The temperature dependence of the distribution of the magnetic moment in an amorphous magnet, where the exchange interactions and the magnitude of the magnetic moment at O K are random variables, has been investigated. In particular, we considered the two-limiting cases, the one with the fixed spin and the other with the fixed interaction.
