Ultrathin Ni films with perpendicular magnetic anisotropy were deposited on Cu(100) at room temperature. The magnetic properties of the films were measured upon multiple magnetization reversals in an alternating magnetic field using the magneto-optic Kerr effect. All magnetic properties remain virtually constant for up to 106 magnetization reversals for all films studied. This finding is supported by a simple theoretical model.
