| 摘 要： | 在La0.67Ga0.33MnO3中用Dy和Yb对La进行了部分替代，随替代量的增加，材料的居里温度单调下降。掺Dy使峰值电阻迅速增加，而Yb的掺杂对电阻率的影响较小，说明样品的磁性和输运性质受掺杂离子的影响。

| Abstract: | La in La0.67Ca0.33MnO3 has been partially substituted by Dy and Yb. With increasing doping amounts, the Curie temperature decreases monotonically. When La is substituted by Dy, the peak resistivity increases rapidly while it is suppressed by Yb doping. This indicates that the size effect of doping ions is related to the specie of rare-earth ions. |
