Research Abstract

This research was focused on an controlling of spins in semiconductor using magneto-electric (ME) material : Cr_2_O3, which can be controlled their magnetic or ferroelectric properties can be controlled by an external electric or magnetic field. In this purpose, we prepared Cr_2O_3/ferromagnetic/CeO_2/Si MIS capacitor. We revealed that the capacitor can be controlled an amount of injected charge depending on an external magnetic and electric field applying.
