Abstract

To study the magnetization reversal mechanism and the magnetic properties of Co/Pd multilayers fabricated at various Ar sputtering pressures, we first demagnetized the samples using the field-demagnetization method, then measured initial and magnetization curves and minor loops. The coercivity and the perpendicular magnetic anisotropy were obtained from the parallel and perpendicular magnetization curves measured at different temperatures. We interpret our experimental results by applying several qualitative methods. From this study, we found that the domain wall pinning with a small pinning site is the dominant magnetization reversal mechanism.
