Effect of oxygen deficiencies on magnetic properties of epitaxial grown BaFeO/sub 3/ thin films on (100) SrTiO/sub 3/ substrates

BaFeO/sub 3/ (BFO) epitaxial thin films on [001] SrTiO/sub 3/ substrates have been successfully produced by pulsed laser beam deposition. The epitaxially grown BFO was found to have tetragonal crystal structure with some amount of oxygen deficiencies. The magnetic susceptibilities of the samples strongly depended on the (hkl) directions of BFO varied in accordance with the crystalline directions, i.e., /spl chi//sub (100)/
