Effects of rapid thermal annealing on the magnetic properties of CoSiB/Pd multilayers with perpendicular anisotropy
The perpendicular magnetic anisotropic property of amorphous CoSiB/Pd multilayers was studied as a function of the thicknesses of the CoSiB and the number of repeated CoSiB/Pd bilayers. In this study, we inves...
