The possibilities of controlled exposure to ion irradiation (He + with an energy 20 keV and a fluence in the range from 3·10 14 15 cm -2 ) as method for modifying magnetic properties domain structure Co 0.35 Pt 0.65 thin ferromagnetic films have been studied. It was found that causes change Dzyaloshinskii--Moriya interaction constant skyrmion density correlates it. This result shows possibility...

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...

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 ...

We use magnetic thin film hard/non/soft-magnetic trilayer systems to probe the nature of the hard–soft phase interaction and the role played by dipolar fields in onedimensional (d) magnetic systems. We have systematically A.J. Zambano ( ) · H. Oguchi · I.

We report the first demonstration of current-induced magnetization switching in a perpendicularly magnetized A1 CoPt single layer. show that good perpendicular magnetic anisotropy can be obtained over wide composition range Co1?xPtx layers, which allows fabrication layer with gradient breaks inversion symmetry structure. By fabricating gradient, we were able to evaluate spin-orbit torque (SOT) ...
