| Outline of Final Research Achievements |
Multiferroic materials have attracted considerable attentions due to their possible application for magnetoelectric memory devices. BiFeO3 is perhaps the most extensively studied multiferroic material because it exhibits prominent mutiferroic properties at room temperature, In this study, we developed study about non-volatile memory effects in this material, and realized this phenomenon in the ferromagnetic and ferroelectric state. We also clarified microscopic origin for this effect.
In the study of Ba2CuGe2O7, we studied magnetoelectric effects and ultrasound transmission in high magnetic fields. Through these experiments, we clarified field control of hybridization between Cu 3d and O 2p orbitals plays a key role in the magnetoeectric effect even in this quantum spin magnet.
