Correlation between structural order parameter of epitaxial Fe/Pt multilayer and corresponding perpendicular magnetic anisotropy and orbital magnetic moment upon annealing

In a Pt/Co/Ir/Co/Pt synthetic ferrimagnet with perpendicular magnetic anisotropy, stochastically occurring peak of magnetic moment was detected in the rapidly increasing magnetic field of 16 kOe / s sweep rate at T = 300 K. The peak arises at the coinciding switching fields between three equilibrium magnetization states. The reason of the peak is nucleation of the nonequilibrium magnetic domains in the vicinity of structural defects of the Co film, where diminished activation energy of magnetic nucleation takes place.

Substrate Temperatures

There is currently great interest in magnetic multilayer (ML) thin films (see e.g.), because they display some interesting magnetic properties. Co/Pd and Co/Au ML systems exhibit perpendicular magnetic anisotropy below certain Co layer thicknesses, which makes them candidates for applications in the field of magneto-optical recording. It has been found that the magnetic anisotropy of a particular system strongly depends on the preparation method (vapour deposition, sputtering, ion beam sputtering) as well as on the substrate, underlayer and deposition temperature. In order to get a better understanding of the correlation between microstructure and properties a thorough cross-sectional transmission electron microscopy (XTEM) study of vapour deposited Co/Pd and Co/Au (111) MLs was undertaken (for more detailed results see ref.).The Co/Pd films (with fixed Pd thickness of 2.2 nm) were deposited on mica substrates at substrate temperatures Ts of 20°C and 200°C, after prior deposition of a 100 nm Pd underlayer at 450°C.
