Emergence of highly degenerate excited states in frustrated magnet MgCrO
K. Tomiyasu, T. Yokobori, Y. Kousaka +5
High degeneracy in ground states leads to the generation of exotic zero-energy modes, a representative example of which is the formation of molecular spin liquid-like fluctuations…
Zn-induced spin dynamics in overdoped LaSrCuZnO
Stephen D. Wilson, Z. Yamani, Chetan Dhital +7
Spin fluctuations and the local spin susceptibility in isovalently Zn-substituted LaSrCuZnO (, ) are measured via inelastic neut…
Inelastic neutron scattering study of the magnetic fluctuations in SrRuO
K. Iida, M. Kofu, N. Katayama +9
By performing time-of-flight neutron scattering measurements on a large amount of single crystals of SrRuO, we studied detailed structure of the imaginary part of the dynam…
Molecular spin-liquid state in spin-3/2 frustrated spinel HgCrO
K. Tomiyasu, H. Ueda, M. Matsuda +3
A hexamer-type spin excitation seen in spinel chromates CrO ( = Mg, Zn, or Cd) is the representative spin-liquid-like state caused by geometrical frustration. To clar…
Incommensurate spin fluctuations in hole-overdoped superconductor KFe2As2
C. H. Lee, K. Kihou, H. Kawano-Furukawa +9
A neutron scattering study of heavily hole-overdoped superconducting KFeAs revealed a well-defined low-energy incommensurate spin fluctuation at [),0] with =…
Molecular spin resonance in the geometrically frustrated MgCr2O4 magnet by inelastic neutron scattering
K. Tomiyasu, H. Suzuki, M. Toki +4
We measured two magnetic modes with finite and discrete energies in an antiferromagnetic ordered phase of a geometrically frustrated magnet MgCr2O4 by single-crystal inelastic neut…
