中文摘要Magnetic properties and spin state transfer in Ga doping perovskite cobaltites La0.7Ca0.3(Co1-yGay)O-3 (y=0, 0.1, 0.2, 0.3, and 0.4) are carefully investigated in this work. On Ga doping, the Curie temperature sharply decreases and the magnetization is greatly reduced, indicating Ga doping breaks the ferromagnetic interaction in the system. For y >= 0.2, the ferromagnetic and antiferromagnetic transitions have been observed in thermal magnetization measurement whereas the dominated antiferromagnetic interaction is confirmed by the negative Curie Weiss temperatures. Evaluation of the effective moment of Co ions seems to imply that Ga doping stablizes Co-ion high spin state. (C) 2010 American Institute of Physics. [doi:10.1063/1.3448011]
