X-ray spectroscopy study of the quantum spin liquid candidate, TbInO3

ORAL

Abstract

Quantum spin liquids (QSL) represent a unique class of frustrated magnetic materials that are on the cutting edge of research, with potential applications ranging from topological quantum computing to unconventional superconductivity. Realizing QSL candidates in thin film geometry is fundamental towards these future technological implementations[1,2]. Our collaborators have synthesized the first thin films of TbInO3, a promising new multifunctional QSL candidate which also hosts improper ferroelectricity and exotic carrier transport at high temperature[3,4]. Here, we deploy advanced x-ray spectroscopy tools to characterize the magnetic and electronic properties in thin films of TbInO3. Our x-ray magnetic circular dichroism (XMCD) and resonant inelastic x-ray scattering (RIXS) experiments at the Tb L-edge shed light on how 4f-5d hybridization influences the magnetic exchange interactions in TbInO3[5].
