| 中文摘要 | The structure, magnetic, and transport properties of La0.5Ca0.5Mn1-xMxO3 (0 less than or equal tox less than or equal to0.1) with M=Ge and Sn have been investigated systematically. A significant lattice expansion is observed in the Sn-doped samples, but not in the Ge-doped ones. At the same time, a substitution of Mn by Ge has little effect on Curie temperature (T-C), but increases the metal-insulator transition temperature (T-P). In contrast, the T-C decreases sharply for Sn doping, while the T-P shows an increase for x <0.02 and a decrease for x >0.02. Compared with Ge doping, Sn doping is more effective in destroying the charge-ordered state. The difference in local lattice distortions due to the Ge and Sn doping is believed to be responsible for the present observations. (C) 2000 American Institute of Physics. [S0021-8979(00)01522-X]. |
