Spin spirals and charge textures in transition-metal-oxide heterostructures discovered by resonant x-ray scattering

Alex Frano

Max Planck Institut

The Fermi surface of a metal, which determines most of its macroscopic properties, can become unstable at low temperatures to the formation of spin or charge density waves, superconductivity, or other collective electronic ordering phenomena.  Understanding and tailoring these ordered states in transition-metal-oxides using hetero-epitaxial growth techniques has become a major field in condensed matter research, but experimentally unraveling their microscopic details remains a challenge.  

In this talk, I will present evidence of novel spin and charge density wave order in nickelate and cuprate heterostructures, respectively.  Using the powerful technique of resonant x-ray scattering, the nature of these ordered patterns will be uncovered.  In addition, I will present a potential outlook for further controlling these ground states.
