中文摘要
本研究的目的是利用先进的透射电镜技术揭示在多铁化合物中观察到的奇异现象的机制。课课组报道了锰矿石中巨磁电阻的潜在机制、外加电场诱导的畴切换现象以及在纳米尺度上确定磁参数的新方法等重要成果。
英文摘要
The aim of this study is to reveal the mechanism of exotic phenomena observed in multi-ferroic compounds by using advanced techniques related with transmission electron microscopy. Our research group has reported important results such as on the underlying mechanism of colossal magnetoresistance in manganites, domain switching phenomena induced by an applied electric field, and a new method that determines magnetic parameters in nanometer-scale area.
