M. Yu et Y. Kakehashi, SPIN-GLASS AND FERROMAGNETISM IN AMORPHOUS FE-M (M=ZR, Y) ALLOYS, Journal of magnetism and magnetic materials, 144, 1995, pp. 289-290
The formations of spin glass and ferromagnetism in amorphous Fe-M (M =
Zr, Y) alloys have been clarified on the basis of the finite-temperat
ure theory of amorphous magnetic alloys: the spin glass is caused by t
he nonlinear magnetic couplings between Fe local moments, while the fe
rromagnetism is realized by the atomic size effect.
