"Spin and orbital interactions in complex oxide heterostructures and transient states probed by x-rays"
ABSTRACT:

The spin and orbital degrees of freedom play a crucial role in determining the remarkable properties of transition metal oxide materials. In this talk, I will describe how resonant inelastic x-ray scattering (RIXS) opens up important new possibilities for measuring these degrees of freedom even in challenging cases such a heterostructures and transient states [1]. This includes determining how orbitals are modified within LaNiO3-based heterostructures [2] and characterizing the spin behavior within the ultra-fast transient state of photo-doped Sr2IrO4 [3].
