Roberts Hall, 210
Professor Yves Idzerda from the Physics Department at MSU will present "Seeing Spin".
He is a candidate for the Physics Department Head position.
The electron spin is an intrinsic form of angular momentum and does not have an analog in classical mechanics. It gives rise to the famous Pauli exclusion principle, Thomas precession, and the technologically important field of spin transport electronics (garnering the Nobel Prize for Peter Grunberg and Albert Fert in 2007). In this talk I will outline methods to characterize electron spin in material systems using circular polarized X-rays. I will discuss the current limits (spatially-resolved and time-resolved) and identify experiments that advanced our understanding of the use of electron spin in technologically important systems including magnetic recording, spin-dynamics, and spin-diffusion. I will show how theory and experiment can mutually drive each other and I will conclude with an outlook on the future of spin-transport electronics and the new X-ray sources in construction.
