DESCRIPTION:Prof. P. Gambardella\,  Department of Materials\, ETH Züric
 h\nThe coupling of spin and orbital angular momenta underlies the magneto
 electric properties of matter. Although small\, the spin-orbit interactio
 n determines the equilibrium properties of magnets as well as the possib
 ility to excite the magnetization out of equilibrium while ensuring the c
 onservation of angular momentum. In this talk\, I will review prominent m
 echanisms due to spin-orbit coupling that give rise to spin currents in 
 ferromagnetic and antiferromagnetic heterostructures\, showing how unusual
  magnetoresistance and spin torque phenomena emerge from charge-spin con
 version in these materials. Finally\, I will present recent results based
  on pump-probe magneto-optic experiments that allow us to measure the spi
 n Hall effect in nonmagnetic conductors and image current-induced magnet
 ization switching of ferromagnetic dots on a timescale of 100 ps.
