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…
Magnetic Excitations in Non-Collinear Antiferromagnetic Weyl Semimetal
Pyeongjae Park, Joosung Oh, Klára Uhlířová +10
has recently attracted considerable attention as a magnetic Weyl semimetal exhibiting concomitant transport anomalies at room temperature. The topology of the e…
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…
Magnetic excitations in bulk multiferroic two-dimensional triangular lattice antiferromagnet (Lu,Sc)FeO
J. C. Leiner, Taehun Kim, Kisoo Park +7
Non-collinear two-dimensional triangular lattice antiferromagnets (2D TLAF) are currently an area of very active research due to their unique magnetic properties, which lead to non…
Magnetic excitations of the Cu quantum spin chain in SrCuPtO
J. C. Leiner, Joosung Oh, A. I. Kolesnikov +10
We report the magnetic excitation spectrum as measured by inelastic neutron scattering for a polycrystalline sample of SrCuPtO. Modeling the data by the 2+4 spinon contribu…
Magnon-phonon coupling and two-magnon continuum in two-dimensional triangular antiferromagnet CuCrO2
Kisoo Park, Joosung Oh, Jonathan C. Leiner +4
CuCrO2 is a manifestation of a two-dimensional triangular antiferromagnet which exhibits an incommensurate noncollinear magnetic structure similar to a classical 120 degree orderin…
