Abstract

Field dependences of the magnetic circular dichroism at the Mn:K edge and RE:L₂,L₃ edges in colossal magnetoresistive perovskites La_0.67-yRE_yCa_0.33MnO₃ (y = 0, Tb-doped y = 0.1, 0.22 and Nd-doped y = 0.33) are reported. Ferromagnetically ordered compounds show a similar dependence for the Mn and RE magnetic sublattices, in contrast to the cluster glass (y = 0.22) compound which revealed a weaker Mn-RE magnetic coupling. By comparison of X-MCD and VSM magnetometry an estimate of the relative amount of manganese atoms in the metallic ferromagnetic regions is obtained.
