Abstract
Certain alloys of FexCr1−x (0.18c. Studies of the critical scattering on polycrystalline samples show a peak at Tc for all x’s and a monotonically decreasing intensity for Tc for x≳0.30. For those x’s exhibiting spin‐glass behavior, there is an increase in intensity at low temperatures. The dynamical studies reveal well‐defined spin waves within the ferromagnetic regime but as T approaches the spin‐glass phase, the magnetic stiffness decreases dramatically.This publication has 8 references indexed in Scilit:
