Ni thickness influence on magnetic properties (Co/Ni/Co/Pt) multilayers with perpendicular magnetic anisotropy

•New material based on (Co/Ni/Co/Pt) multilayer with perpendicular magnetic anisotropy is investigated.•The magnetic properties were investigated in (Co/Ni/Co/Pt) with different Ni thickness.•From magnetometry measurements, micromagnetic simulation and temperature dependence of intrinsic properties, Block constant and spin wave stiffness were determined for each sample.
