Description

Abstract:
Magnetic interactions are central to many current topics in condensed matter physics, including the mechanism of high-Tc superconductivity, entanglement in quantum spin liquids, and the development of spintronic devices. Pressure is a key thermodynamical variable in the study of magnetism, but the complex high pressure sample environment largely limits the use of standard experimental techniques such as magnetic susceptibility and neutron scattering. In this context, hard x-ray probes of magnetism have had substantial impact. In this presentation, I will describe the high-pressure magnetic x-ray spectroscopy and scattering capabilities available at the 4-ID-D beamline, highlighting a few recent results, and our ongoing development of x-ray emission magnetic circular dichroism instrumentation. Finally, I will discuss current and planned developments on high-pressure technology that are focused on enabling the full use of the APS-U POLAR beamline capabilities.
