摘要：

We have studied the magnetic properties of the Co/Cu(110) system (5 ML < d(Co) < 40 ML) at 300 K, using the magneto-optic Kerr effect. The magnetic easy axis is found to switch through 90 degrees for a constant Co thickness, typically over a period of one hour. We attribute this behavior to the reversal in sign of the effective in-plane uniaxial anisotropy constant, due to the adsorption of submonolayer quantities of residual CO gas in the UHV chamber. Scanning tunnel microscope images reveal the growth of elongated island structures preferentially oriented along the [001] direction providing edges for gas adsorption.
