Spin-orbit-lattice entangled state in AMgReO (A = Ca, Sr, Ba) revealed by resonant inelastic X-ray scattering
Felix I. Frontini, Graham H. J. Johnstone, Naoya Iwahara +7
The ordered double perovskites present an exotic playground for studying novel multi-polar physics due to large spin-orbit coupling. We present Re L3 edge resonant inelastic…
Strongly Gapped Spin-Wave Excitation in the Insulating Phase of NaOsO3
S. Calder, J. G. Vale, N. Bogdanov +13
NaOsO3 hosts a rare manifestation of a metal-insulator transition driven by magnetic correlations, placing the magnetic exchange interactions in a central role. We use resonant ine…
