摘要
The grain size-dependent magnetism in fine particle perovskite, La1-xSrxMnO3 (0.1 < x < 0.55), has been investigated. For the samples with different concentrations, different grain size-dependent magnetism has been observed. Meanwhile, different grain size dependencies of lattice distortions and structure phase transitions have also been observed for the various doped samples. The phenomena suggest a structure-coupled change of magnetism in the double exchange perovskite. (C) 1999 Elsevier Science Ltd. All rights reserved.
