Neutron Scattering Studies of the Breathing Pyrochlore Antiferromagnet LiGaCrO
Zheng He, Yiqing Gu, Hongliang Wo +7
We report neutron scattering measurements of the spinel oxide LiGaCrO, in which magnetic ions Cr form a breathing pyrochlore lattice. Our experiments reveal the…
Heisenberg spins on an anisotropic triangular lattice: PdCrO2 under uniaxial stress
Dan Sun, Dmitry A. Sokolov, Richard Waite +6
When Heisenberg spins interact antiferromagnetically on a triangular lattice and nearest-neighbor interactions dominate, the ground state is 120 antiferromagnetism. In th…
Crystal Electic Field and Possible Coupling with Phonon in Kondo lattice CeCuGa3
V. K. Anand, A. Fraile, D. T. Adroja +8
We investigate the magnetic and crystal electric field (CEF) states of the Kondo lattice system CeCuGa3 by muon spin relaxation (muSR), neutron diffraction, and inelastic neutron s…
Randomness and Frustration in a S = 1/2 Square-Lattice Heisenberg Antiferromagnet
Ellen Fogh, Otto Mustonen, Peter Babkevich +7
We explore the interplay between randomness and magnetic frustration in the series of Heisenberg square-lattice compounds SrCuTeWO. Substituting W for…
Metastable antiphase boundary ordering in CaFeO
H. Lane, E. E. Rodriguez, H. C. Walker +11
CaFeO is an antiferromagnet exhibiting two magnetic orders which shows regions of coexistence at some temperatures. Using a Green's function formalism, we model…
Magnetic field induced quantum spin liquid in the two coupled trillium lattices of KNi(SO)
Ivica Zivkovic, Virgile Favre, Catalina Salazar Mejia +19
Quantum spin liquids are exotic states of matter which form when strongly frustrated magnetic interactions induce a highly entangled quantum paramagnet far below the energy scale o…
