Interfacial coupling effect of Cr₂O₃ on the magnetic properties of Fe₇₂Ga₂₈ thin films.

ABSTRACT: Here it is investigated the effect of the antiferromagnet Cr₂O₃ on the magnetic properties of ferromagnetic Fe₇₂Ga₂₈ thin films. Sputtered Fe₇₂Ga₂₈ layers have their magnetization in the sample plane with a magnetic fluctuation that gives rise to magnetic ripple. In order to turn its magnetization into the out of plane (OOP) direction, it has been magnetically coupled with Cr₂O₃ that has magnetic moments along the c-axis, that is the perpendicular direction when properly aligned. Cr₂O₃ has been obtained from Cr oxidation, whereas Fe₇₂Ga₂₈ has been deposited on top of it by sputtering in the ballistic regime. Although a uniaxial in-plane magnetic anisotropy is
