Extract

Submonolayer films of Mn grown on fcc Co(001) are ferromagnetically ordered with the magnetization direction oriented parallel to the Co substrate magnetization. After exposure to oxygen the Mn atoms remain ferromagnetically ordered but their magnetization direction rotates 180 degrees and is now aligned antiparallel to the Co magnetization. This behavior in magnetic coupling between the Mn and Co films is not consistent with recent theoretical predictions.
