Gd interactions in (Ce,Gd)Al3

Abstract
The susceptibility of Ce1x Gdx Al3 for 0.08≤x≤0.9 has an anomaly which resembles that associated with a spin-glass transition. For x greater than the percolation threshold concentration for antiferromagnetism at x≊0.5, the size of the susceptibility anomaly decreases two orders of magnitude and a resistivity anomaly appears.
