Synthesis, Structural and magnetic properties of the solid solution (CuCl1-xBrx)LaNb2O7 (0<x<1)
Yoshihiro Tsujimoto, Atsushi Kitada, Hiroshi Kageyama +8
The two-dimensional (2D) quantum spin system (CuCl)LaNb2O7 has a spin-singlet ground state with a gap of 2.3 meV, while the isostructural material (CuBr)LaNb2O7 displays collinear…
Magnetic Excitations of the Spin Gap System TlCuCl
A. Oosawa, T. Kato, H. Tanaka +3
TlCuCl has a singlet ground state with the excitation gap meV. The magnetic excitations in TlCuCl have been investigated by means of neutron inelastic scattering e…
Dzyaloshinski-Moriya Interaction in the 2D Spin Gap System SrCu2(BO3)2
O. Cepas, K. Kakurai, L. P. Regnault +6
The Dzyaloshinski-Moriya interaction partially lifts the magnetic frustration of the spin-1/2 oxide SrCu2(BO3)2. It explains the fine structure of the excited triplet state and its…
Direct Evidence for the Localized Single-Triplet Excitations and the Dispersive Multi-Triplets Excitations in SrCu2(BO3)2
H. Kageyama, M. Nishi, N. Aso +6
We performed inelastic neutron scattering on the 2D Shastry-Sutherland system SrCu2(11BO3)2 with an exact dimer ground state. Three energy levels at around 3, 5 and 9 meV were obse…
Magnetic Excitations in the Spin Gap System TlCuCl
A. Oosawa, T. Kato, H. Tanaka +5
Single-crystal neutron inelastic scattering was performed in order to investigate the magnetic excitations in the spin gap system TlCuCl. The constant- energy scan pro…
Critical neutron scattering study of the compositional phase transition in Mg-doped CuGeO3
M. Nishi, H. Nakao, Y. Fujii +3
Cu1-xMgxGeO3 undergoes a first-order phase transition at a critical concentration xc between an antiferromagnetic (AF) state on dimerized lattice (D-AF) and an AF Neel state on und…
