Heavy-Fermion, Kondo, Spin Glass-Like, and Antiferromagnetic Behavior in (Ce,Gd)Al/sub 3/

摘要

We have found that Ce/sub 1-x/Gd/sub x/Al sub 3 with x = 0.23 is a heavy-fermion system which undergoes a spin glass transition. The amplitude of the peak in the susceptibility that characterizes the spin glass transition passes through a sharp maximum at x = 0.5. For x = 0.635 and 0.77 the system undergoes a spin glass-like transition at 100 deg K and an antiferromagnetic transition at 20 deg K. (ERA citation 12:008348)
