N. Hegman et al., BROAD PEAK OF THE NONLINEAR SUSCEPTIBILITY AT THE SPIN-GLASS TEMPERATURE OF AMORPHOUS FE93ZR7, Journal of physics. Condensed matter, 6(31), 1994, pp. 120000427-120000430
The broad peak of the non-linear AC susceptibility around the spin-gla
ss temperature (T(g)) of amorphous Fe93Zr7 suggests that the paramagne
tic to spin-glass transition at T(g) is determined by the superparamag
netic behaviour of magnetic clusters.
