Magnetic properties of Co/MgO multilayered films

Abstract
Multilayered thin films composed of Co and MgO layers were fabricated with an ultrahigh vacuum deposition technique. Magnetization measurements suggest that antiferromagnetic Co oxides do not form at the interface with the MgO layers. An enhancement of the magnetization is observed in a film with the Co layer thickness thinner than 30 Å. The maximum enhancement is about 10% of the bulk magnetization of hcp Co metal in a Co/MgO(22/30 Å) multilayered thin film whose magnetization is 180 emu per gram of Co.
