In this Published 14 7 2022 paper the possible modulation of the magnetic anisotropy and HEB was investigated by the structural parameters of the nanoporous FM AFM KEYWORDS multilayer films. The Co Pd -IrMn multilayers were sputtered on flat SiO2 and self-organized nanoporous oxide Al2O3 TiO2 substrates with Multilayer thin film different pore size and surface morphology. The influence of surface Antidot arrays structure morphology and pore size on the structure and magnetic of the nanoporous Co Pd and Co Pd -IrMn films were investigated carefully. Perpendicular magnetic All films flat and porous ones exhibit strong perpendicular magnetic anisotropy anisotropy and large HEB at room temperature specially in the Perpendicular exchange bias nanoporous TiO2- Co Pd -IrMnfilm. Moreover a significant increase of FM AFM the coercivity as well as a reduction of the remanence of the developed nanoporous thin films which depends on the pore size and surface morphology was also observed.
