Very sensitive magnetization and hysteresis measurements on CuMn call in question, whether the remanent magnetization can be attributed to the whole system of impurity spins responding bodily to external perturbations. - New cycling experiments, which alter the shape of the hysteresis curve drastically, are presented. The results show that the anisotropy energy of CuMn depends on field-treatment and is neither a macroscopic nor a completely intrinsic quantity. © 1984.
