The magnetic properties of a thin film consisting of an exchange-coupled [Co/Ni]2/NiFe multilayer has been studied as a function of the NiFe thickness by using Monte Carlo modeling and compared with experimental results of [Co/Ni]4/Co/NiFe multilayers. Both modeling and experiment showed that the NiFe thickness controls the effective anisotropy. The direction of the easy axis is determined by a...

We report the experimental observation of room-temperature perpendicular magnetic anisotropy ~PMA! in Ni/Pd ~111! multilayer films having the thickness range of 5–11 Å Ni and 4–11 Å Pd sublayers, prepared by direct current magnetron sputtering on glass substrates at Ar sputtering pressure of 7 mTorr. Perpendicular magnetic anisotropy was found to be sensitively dependent on both Niand Pd-sublay...
