Abstract

Pulsed-field magnetization measurements up to 40 T by Faraday rotation were made for random alloy Cd1−xMnx Te with 0.1 < x < 0.5. At liquid helium temperature the magnetization can be separated into the sum of two components: a paramagnetic Brillouin-like part that saturates by B=15 T, and a part linear in B. For large x, the linear part dominates and becomes independent of x. Mean-field calculations suggest that an enhanced magnetization can be obtained with new ordered-alloy crystal structures which have reduced antiferromagnetic cancellations.
