Abstract

The magnetocrystalline anisotropy (MAE) and spin and orbital moments of the (001) surface of bcc Co have been calculated by a first principles theory. The easy axis is found to be [100], in agreement with observations, and the size of the MAE is found to be substantially larger than the corresponding value of bulk bcc Co. The possibility of detecting this large surface MAE is discussed.
