Glasslike phonon excitation caused by ferroelectric structural instability
Y. Ishii, A. Yamamoto, N. Sato +5
Quest for new states of matter near an ordered phase is a promising route for making modern physics forward. By probing thermal properties of a ferroelectric (FE) crystal Ba1-xSrxA…
Spin dynamics and spin freezing in the triangular lattice antiferromagnets FeGa2S4 and NiGa2S4
Songrui Zhao, P. Dalmas de R/'eotier, A. Yaouanc +6
Magnetic susceptibility and muon spin relaxation (muSR) experiments have been carried out on the quasi-2D triangular-lattice spin S = 2 antiferromagnet FeGa2S4. The muSR data indic…
Incommensurate short-range order in the S=1 triangular antiferromagnet NiGa2S4
C. Stock, S. Jonas, C. Broholm +5
Neutron scattering is used to investigate spin correlations in ultra pure single crystals of the S=1 triangular lattice NiGa2S4. Despite a Curie-Weiss temperature of Theta_CW=-80(2…
Unconventional spin freezing and fluctuations in the frustrated antiferromagnet NiGa2S4
D. E. MacLaughlin, Y. Nambu, S. Nakatsuji +4
Muon spin rotation (muSR) experiments reveal unconventional spin freezing and dynamics in the two-dimensional (2D) triangular lattice antiferromagnet NiGa2S4. Long-lived disordered…

Peter G. O. Freund, Charles J. Goebel, Yoichiro Nambu +1
We review the life and remarkable contributions to Physics of Gregor Wentzel.
Unusual superexchange pathways in a Ni triangular lattice of NiGaS with negative charge-transfer energy
K. Takubo, T. Mizokawa, J. -Y. Son +5
We have studied the electronic structure of the Ni triangular lattice in NiGaS using photoemission spectroscopy and subsequent model calculations. The cluster-model analysi…
