- 論文の詳細を見る
The magnetization behaviors of La0.7-xYxPb0.3MnO3 ($0.0\leq x\leq 0.2$) have been examined. The replacement of La ions by Y results in a considerable decrease in the ferromagnetic ordering temperature $T_{\text{C}}$ and irreversible behavior in the zero-field cooling and field cooling curves at a low applied field. The saturation magnetization $M_{\text{S}}$ decreases as Y content increases. The results can be explained by the suppression of ferromagnetism due to structure tuning induced by the substitution of Y into the La site.
