Enhancement of the magnetic hysteresis in ultrathin PdNi films by hydrogen absorption-desorption cycling

Measurements of the magnetic hystereis in ultrathin Pd Ni films (d < = 100A) show a marked increase of the perpendicular coercitive field after hydrogen absorption--desorption cycling; a squaring up of the magnetic hysteresis is observed at the same time. This is tentatively attributed to an irre...

Summary:Measurements of the magnetic hystereis in ultrathin Pd Ni films (d < = 100A) show a marked increase of the perpendicular coercitive field after hydrogen absorption--desorption cycling; a squaring up of the magnetic hysteresis is observed at the same time. This is tentatively attributed to an irreversible change of the stress state of the film, in relation with the film--substrate interaction. 11 ref.--AA
