Magnetic heat capacity of an amorphous Gd-Al alloy
Abstract
The magnetic specific heat of amorphous GdAl2 shows a broad maximum near 17.5 K, the temperature of the spin-glass-like cusp in the magnetic susceptibility. At low temperatures it varies as T 3 2, with a small negative intercept. This is interpreted in terms of ferromagnetic spin waves excited in regions some 35 Å in size. © 1977.
