Lf. Kiss et N. Hegman, FREQUENCY-DEPENDENCE OF AC SUSCEPTIBILITY OF AMORPHOUS FE93ZR7 ALLOY, Journal of magnetism and magnetic materials, 144, 1995, pp. 293-294
The ac susceptibility chi(ac) of the amorphous spin-glass-like Fe93Zr7
alloy was measured at low temperatures in a wide frequency range of 6
0 Hz to 100 MHz. The frequency dependence of the spin-glass temperatur
e Tg can be well described by a Fulcher-type expression, It points to
the non-equilibrium nature of the spin-glass transition in this alloy.
