Abstract

The crystal and magnetic structures of the (Nd_1-xSr _x)(Mn_1-xRu_x)O₃ perovskites have been studied by neutron powder diffraction and muon spin relaxation. The simultaneous and consistent doping of the A- and B-sites with Sr and Ru has been used for avoiding the Mn⁴⁺ formation and hence, suppression of the double exchange. All studied samples (0≤×≤0.875) are insulators and show unusual long-range ferromagnetic state, which can be called "statistical ferrimagnet," with antiferromagnetic coupling between Mn and Ru magnetic moments, and ferromagnetic coupling in the Mn-Mn and Ru-Ru pairs.
