Oscillatory Magnetic Anisotropy and Quantum Well States in Cu/Co/Cu(100) Films

The magnetic anisotropy of Co films grown on stepped Cu(100) substrates is found to oscillate with varying Cu overlayer thickness. We relate these oscillations to the occurrence of quantum well states in the Cu overlayer.
