Structure and magnetic properties of Fe2O3-FeTiO 3 films

Abstract

Solid solutions between ilmenite (FeTiO3) and hematite (α-Fe2O3) are one of the candidates for high-temperature magnetic semiconductors. Well-crystallized epitaxial xFeTiO3-(1-x)Fe2O3 (0.5 <0.7 had large saturation magnetization at room temperature. The magnetic easy plane lay in the (001) crystallographic plane regardless of the film orientations. The magnetic properties of (001)- and (110)-oriented films seemed to be affected not only by the crystalline orientation but also by the lattice strains induced in the films. © 2010 IOP Publishing Ltd.
