Magnetic stripe domains of [Pt/Co/Cu]10 multilayer near spin reorientation transition

Magnetic stripe domains of [Pt/Co/Cu]10 multilayer near spin reorientation transition

The dependence of magnetic anisotropy, magnetic domain patterns and magnetization reversal processes in [Pt/Co(tCo)/Cu]10 film stack epitaxied on Cu (111) substrate have been studied as a function of the Co layer thickness tCo, by magneto-optic polar Kerr magnetometry and microscopy. We find the fil...
