Signature of BKT-like spin transport in a quasi-2D antiferromagnet BaNiVO
Kurea Nakagawa, Minoru Kanega, Tomoyuki Yokouchi +2
In two-dimensional (2D) spin systems, the augmentation of spin fluctuations gives rise to quasi-long-range order; however, how they manifest in spin transport remains unclear. Here…
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…
Microscopic theory of spin Seebeck effect in antiferromagnets
Keisuke Masuda, Masahiro Sato
We develop a microscopic theory for the spin Seebeck effect (SSE) in Néel and canted phases of antiferromagnetic insulators. We calculate the DC spin current tunneling from the ant…
Zigzag chain order of LiVSe developing away from the vanadium trimer phase transition boundary
K. Kojima, N. Katayama, K. Sugimoto +3
The phenomenon of self-assembly of constituent elements to form molecules at low temperatures appears ubiquitously in transition metal compounds with orbital degrees of freedom. Re…
Vibronic effect on resonant inelastic x-ray scattering in cubic iridium hexahalides
Naoya Iwahara, Wataru Furukawa
In resonant inelastic x-ray scattering (RIXS) spectra of KIrCl, the peak for the multiplet states shows a splitting that resembles non-cubic crystal-field effect al…
Phase diagram of the Kitaev-Heisenberg model using various finite-size clusters
Masahiro Kadosawa, Masaaki Nakamura, Yukinori Ohta +1
We estimate phase boundaries of four ordered and two spin-liquid phases for the spin- Kitaev-Heisenberg (KH) model using four kinds of relatively-small clusters, based…
