Triple Points

We had established that the non-monotonic magnetic relaxation appeared, when two or three magnetic fields, switching between stable magnetization states, coincide with each other, in Pt/Co/Ir/Co/Pt synthetic ferrimagnets with perpendicular magnetic anisotropy. Switching fields between stable magnetization states depend on sum of exchange interlayer energy, Zeeman energy and magnetization reversal energy barrier of each layer. This total energy depends on layers thickness and temperature. We had shown that with choose of temperature and free layer thickness we can achieve double or triple points on energy states diagram, which is reason of nonmonotonic magnetization relaxation.

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.
