Reversible spin-reorientation transition in Co0.35 Pd0.65/Pd multilayer films

Abstract We report a reversible spin-reorientation transition between in-plane and out-of-plane orientation in Co 0.35 Pd 0.65 /Pd multilayer films, in situ measured with magneto-optical Kerr effects upon alternate depositions of the ultrathin CoPd and Pd layers. A misfit-strain modulation produced by the depositions of the alternating constituent layers might be one of promising candidates to controllably engineer spin orientations without applying an external magnetic field.
