AB - An approach to fabrication of a patterned magnetic recordingmedium for next generation data storage systems is presented.(Co/Pd)n magnetic multilayers are evaluated as candidates for patterned medium materialsfor their high and easily controllable magnetic anisotropy. The multilayer filmsdeposited on a Ta seed layer enable high intergranular exchange couplinganessential feature of a patterned magnetic recording medium. The quality of(Co/Pd)n superlattices was optimized via deposition conditions and monitored using low-angle x-raydiffraction. An estimated in-plane (hard-axis) magnetization saturation field in excess of40000 Oe was observed. Vertical (easy-axis) hysteresis loops for as-deposited continuousmagnetic multilayers exhibited a low coercivity of 930 Oe, indicating highly uniform(magnetically) films with weak domain wall pinning. Ion-beam proximity lithographywas used to pattern magnetic multilayers into 43 nm islands on a 135 nm pitch.Following patterning, easy-axis coercivity increased nearly 15-fold to 12.7 kOe.
