Thickness-dependent magnetic properties in Pt/[Co/Ni] n multilayers with perpendicular magnetic anisotropy

“…Magnetic multilayers with strong perpendicular magnetic anisotropy (PMA) and low magnetic damping have attracted much attention because of their potential applications in highdensity magnetic random access memories (MRAM) [1][2][3][4][5] and spin torque nano-oscillators. [6][7][8][9] Compared to the in-plane magnetized ferromagnets, ferromagnetic films with PMA facilitate the realization of nonvolatile MRAM with lower power and higher density storage because the latter has lower critical switching current and higher thermal stability than the former as the continuous downscaling of the cell size of devices. [10] In addition, PMA can be an effective magnetic field to achieve zero external magnetic field working spintorque nano-oscillators with ferromagnets with strong PMA and low damping as its free layer.…”
