Thermal Hall effects due to topological spin fluctuations in YMnO
Ha-Leem Kim, Takuma Saito, Heejun Yang +7
The thermal Hall effect in magnetic insulators has been considered a powerful method for examining the topological nature of charge-neutral quasiparticles such as magnons. Yet, unl…
Coexisting Z-type charge and bond order in metallic NaRuO
Arvind Kumar Yogi, Alexander Yaresko, C. I. Sathish +7
How particular bonds form in quantum materials has been a long-standing puzzle. Two key concepts dealing with charge degrees of freedom are dimerization (forming metal-metal bonds)…
Spin texture induced by non-magnetic doping and spin dynamics in 2D triangular lattice antiferromagnet h-Y(Mn,Al)O3
Pyeongjae Park, Kisoo Park, Joosung Oh +14
Novel effects induced by nonmagnetic impurities in frustrated magnets and quantum spin liquid represent a highly nontrivial and interesting problem. A theoretical proposal of exten…
Renormalization of spin excitations in hexagonal HoMnO3 by magnon-phonon coupling
Taehun Kim, Jonathan C. Leiner, Kisoo Park +5
Hexagonal HoMnO3, a two-dimensional Heisenberg antiferromagnet, has been studied via inelastic neutron scattering. A simple Heisenberg model with a single-ion anisotropy describes…
Symmetry breaking and unconventional charge ordering in single crystal NaRuO
Arvind Yogi, C. I. Sathish, Hasung Sim +3
The interplay of charge, spin, and lattice degrees of freedom in matter leads to various forms of ordered states through phase transitions. An important subclass of these phenomena…
Studies on the high-temperature ferroelectric transition of multiferroic hexagonal manganite RMnO3
Hasung Sim, Jaehong Jeong, Haeri Kim +2
Hexagonal manganites are multiferroic materials with two highly-dissimilar phase transitions: a ferroelectric transition (from P63/mmc to P63cm) at a temperature higher than 1000 K…
