Outline of Final Research Achievements

I investigated chemical substitution effect on magnetic and ferroelectric properties of multiferroic GaFeO3-type oxide thin films. I found that leakage current significantly decreases with Sc doping, resulting in clear ferroelectric hysteresis loops. Furthermore, I found that the magnetic properties are widely controllable via chemical substitution.
