Ferroelectric polarization switching with a remarkably high activation-energy in orthorhombic GaFeO3 thin films

Seungwoo Song, Hyun Myung Jang, Nam-Suk Lee +5

Orthorhombic GaFeO3 (o-GFO) with the polar Pna21 space group is a prominent ferrite by virtue of its piezoelectricity and ferrimagnetism, coupled with magneto-electric effects. Her…
