Magnetic Field-Induced Condensation of Triplons in Han Purple Pigment BaCuSiO
M. Jaime, V. F. Correa, N. Harrison +9
Besides being an ancient pigment, BaCuSiO is a quasi-2D magnetic insulator with a gapped spin dimer ground state. The application of strong magnetic fields closes this gap…
Spin-Vacancy-Induced Long-Range Order in a New Haldane-Gap Antiferromagnet
Y. Uchiyama, Y. Sasago, I. Tsukada +5
Magnetic susceptibility, high-field magnetization and inelastic neutron scattering experiments are used to study the magnetic properties of a new S=1 quasi-1-dimensional antiferrom…
BaCu_2Si_2O_7: a new quasi 1-dimensional S = 1/2 antiferromagnetic chain system
I. Tsukada, Y. Sasago, K. Uchinokura +5
The new antiferromagnetic (AF) compound BaCu_2Si_2O_7 is studied by magnetic susceptibility and neutron scattering techniques. The observed behavior is dominated by the presence of…
Similarity and Difference between Magnetic- and Nonmagnetic-Impurity Effects in Spin-Peierls Cuprate CuGeO_3
N. Koide, Y. Uchiyama, T. Hayashi +5
We have measured the magnetic susceptibility of single-crystal Cu_{1-x}Ni_xGeO_3 to study doping effects of the magnetic impurity (Ni^{2+} has S=1 spin) on the inorganic spin-Peier…
Field-induced Commensurate-Incommensurate phase transition in a Dzyaloshinskii-Moriya spiral antiferromagnet
A. Zheludev, S. Maslov, G. Shirane +3
We report an observation of a commensurate-incommensurate phase transition in a Dzyaloshinskii-Moriya spiral magnet Ba_2CuGe_2O_7. The transition is induced by applying a magnetic…
