| Research Abstract |
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.
