项目摘要
We have investigated on anomalous magneto-transport properties as spin-charge coupled phenomena in pyrochlore molybdates. We have succeeded in the synthesis of electron-filling controlled crystals by fine tuning of the condition for high pressure synthetic method, in which the diffusive paramagnetic metal state quite similar to that of under high pressure can be realized at ambient pressure. We have shown that the Berry's phase based on the real-space picture contributes to the anomalous Hall effect even in the paramagnetic diffusive state in (Y, Tb, Cd)2Mo2O7 with diluted spin chirality.
本文研究了辉绿盐钼酸盐中自旋-电荷耦合现象的异常磁输运性质。通过对高压合成方法条件的微调,我们成功地合成了电子填充控制晶体,在环境压力下可以实现与高压下非常相似的顺磁性金属扩散态。我们已经证明,在(Y, Tb, Cd)2Mo2O7中,即使在顺磁扩散状态下,在自旋手性被稀释的情况下,基于实空间图像的Berry相也会导致反常霍尔效应。
