摘要

We report on the reversible change of the magneto-optical Kerr effect (MOKE) in Pd covered magnetic thin films by controlling H₂ absorption. After H₂ exposure, the extinction angle of MOKE was shifted and correspondingly the Kerr intensity was significantly increased. When properly choosing the analyzer angle, we obtained large enhancement of 40%, 35% and 50-70% for Pd/Fe, Pd/Co and Pd/Ni bilayers, respectively. The time-dependence of this H₂ absorption effect on MOKE was investigated. The reversibility of MOKE enhancement was demonstrated in Pd/Ni bilayer by multiple cycles (at least 4 times) of H₂ absorption and desorption. These observations reveal the universal responses when combining the hydrogenated Pd layer with a magnetic thin film, and can be applied in various magnetic materials.
