ANISOTROPY AND MAGNETO-OPTICAL PROPERTIES OF SPUTTERED Co/Ni MULTILAYER THIN FILMS
AbsrraclSeveral series of sputtered Co/Ni multilayer thin films have been investigated. The volume and interface contributions to the magnetic anisotropy were determined from magnetization measurements, and the interface anisotropy, 6 = 0.23 f 0.03 erg/cm2, was found to support perpendicular magnetic anisotropy. The anisotropy constant, K, increased with the Au buffer layer thickness, indicatin...
متن کاملThe Perpendicular Magnetic Anisotropy of CoPt/Au Multilayer Films
We have studied the magnetic properties of Au (2 nm)/Co50Pt50 (3 nm)/Au (2 nm) multilayer films prepared on amorphous Al2O3/Si and (0 0 1) MgO substrates. The as-deposited films on both substrates are magnetically soft with an FCC structure and exhibit a perpendicular anisotropy. After annealing at 500 °C, the sample on the Al2O3/Si substrate has become magnetically isotropic but the sample on ...
متن کاملExchange Bias in FeF20-CoPt heterosystems with perpendicular anisotropy
The exchange bias e!ect is measured in heterosystems with perpendicular anisotropy consisting of Co/Pt multilayers on top of the (0 0 1) face of a FeF single crystal. The resulting exchange "eld H exhibits a strong dependence on temperature and the axial freezing "eld, H . Within the framework of an Ising-type model, the H vs. 1 as well as the H vs.H data are explained in terms of the microscop...
متن کاملMagnetic and magneto-optical properties of sputtered Co/Pd multilayers
Co/Pd multilayer thin films consisting of Co layers between 2-25 ,~, and Pd layers of typically 14 A were prepared by rf sputtering. Hysteresis loops and the magnetization were measured parallel and perpendicular to the film plane. From these measurements and torque curves it was found that the muitilayers show a transition of the easy axis from an in-plane to a direction perpendicular to the f...
متن کاملMagneto-Electric Control of Surface Anisotropy and Nucleation Modes in L10-CoPt Thin Films
The interplay between electric field-controlled surface magnetic anisotropy and micromagnetic nucleation modes for L10-CoPt thin films is investigated with density-functional and micromagnetic model calculations. The electric field redistributes electron states near the Fermi level, which has a fairly strong effect on the surface anisotropy, but due to inversion symmetry, the net anisotropy of ...
