Spin transfer in high spin-orbit materials Dr Bryan Hickey The spin Hall magnetoresistance is the result of a spin current, developed in a high spin orbit material such as Pt or W, exerting a spin transfer torque on the magnetization of an adjacent material. Understanding the details of this effect is currently a very active area of research in spintronics. Theory predicts that the effect only depends on the orientation of the magnetization of the magnetic layer and that the magnitude of the effect is dominated by the spin Hall angle and the spin-mixing conductance. In recent measurements that we have made, it turns out that the simple picture will not explain the observations. It appears that the magnitude of the magnetization is important and that the temperature dependence although complicated, reveals many new details. This PhD project will continue the initial work we have completed and in conjunction with our theory collaborators, will reveal the fundamental properties of these spin effects. We will then be in a position to test the predictions on how to generate spin amplification and switching.
