seminar – Skew scattering and the spin Hall effect in cooperatively ordering magnetic systems

On November 16 at 14:00, Timothy Ziman from Institut Laue Langevin Theory Group will give us an on-line seminar entitled :

Skew scattering and the spin Hall effect in cooperatively ordering magnetic systems

Link to the seminar using Skype Meeting or in case of failure or with mobilephone Skype Web App

The spin Hall effect is affected by the Coulomb interaction as well as spin–spin correlations in metals. I will discuss the impact on the spin Hall effect from cooperative effects, firstly in an itinerant ferromagnet where there is an anomaly near the Curie temperature originating from high-order spin fluctuations. The second case considered is a metallic spin glass, where exchange via slowly fluctuating magnetic moments may lead to the precession of an injected spin current. This decreases the net spin-charge conversion from skew scattering at temperatures below a value three or four times the freezing temperature.
