Title

Magnetic induction in Re doped Co35Fe65 alloy thin films

Abstract

The absolute value of magnetization plays an important role in spin dynamics properties of thin films. For example, low damping and the high magnetization of ferromagnetic (FM) materials are used to reduce the critical current density in spin-transfer-torque (STT) devices. Therefore, CoFe alloys, have ultra-low damping, is the most suitable material for STT devices. Apart from this, damping is increased by radiative and eddy-current contribution. These contributions have to be subtracted from total damping and depend on the static properties such as magnetization and resistivity of FM. Damping and magnetization can be tuned by adding rhenium as a dopant and it is very important to understand how the Re concentration influences the damping and magnetization in order to tailor the material's properties. Therefore, the absolute value of the magnetization is extremely important. SuperADAM is a reflectometer with polarisation analysis offering extremely high sensitivity to magnetic structure. This instrument is ideally suited for our measurements. The difference in critical angle between spin up and spin down measurements is directly proportional to the absolute value of magnetization.
