Abstract

We present a study of the magnetization, coercivity, ac susceptibility, and magnetotransport properties of polycrystalline Nd1-xSr xCoO3 (0<x<0.6). The magnetic phase diagram is dominated by a crossover from a semiconducting spin/cluster-glasslike phase at x<0.18 to a phase dominated by long-range ferrimagnetic order and metallic behavior at x>0.18. Aside from the fact that the Nd sublattice orders antiferromagnetically with respect to the Co sublattice giving rise to ferrimagnetism at low temperatures, the phase behavior is remarkably similar to that of the La1-xSrxCoO3 system in all respects. We suggest that this similarity, which is our major finding, derives from the fact that both systems exhibit magnetoelectronic phase separation and that the formation of ferromagnetic clusters, which has recently been experimentally verified in La1-xSrxCoO3, dominates the phase behavior.
