  • Abstract
    To clarify the influence of CoO spins on the magnetic properties of Co-CoO reactive-sputtered films, Co-CoOx compositionally modulated (CM) films were investigated. These Co-CoOx CM films were prepared by modulating the oxygen partial pressure (Po2) in the vacuum chamber. These films have Co-CoO interfaces parallel to the film plane. The coercivity (Hc) and in-plane anisotropy (KH) of CM films with short modulation periods increased remarkably below the Néel temperature of CoO (= 292 K). These increases in Hc and KH at low temperatures are thought to originate in a magnetic interaction between the Co spins and CoO spins.
