Magnetic susceptibility data between 4.2° and 300°K have been obtained for the (Al,Cr) 2 BeO 4 solid‐solution series. Chromium chrysoberyl is antiferromagnetic with a Néel temperature near 28°K; above 60°K it obeys the Curie‐Weiss law with θ= 13OK and an effective atomic moment of 3.2 Bohr magnetons. A four‐sublattice Weiss model consistent with the experimental results is presented.
