Structure of the exotic spin-flop states in BaCu2Si2O7
A. Zheludev, E. Ressouche, I. Tsukada +1
The unusual 2-stage spin flop transition in BaCu2Si2O7 is studied by single-crystal neutron diffraction. The magnetic structures of the various spin-flop phases are determined. The…
Cu Nuclear Quadrupole Resonance Study of the Spin-Peierls Compound Cu1-xMgxGeO3: A Possibility of Precursory Dimerization
Y. Itoh, T. Machi, N. Koshizuka +2
We report on a zero-field 63Cu nuclear quadrupole resonance (NQR) study of nonmagnetic Mg impurity substituted Cu1-xMgxGeO3 (single crystals; the spin-Peierls transition temperatur…
Two-stage spin-flop transitions in S = 1/2 antiferromagnetic spin chain BaCu_2Si_2O_7
I. Tsukada, J. Takeya, T. Masuda +1
Two-stage spin-flop transitions are observed the in quasi-one-dimensional antiferromagnet, BaCuSiO. A magnetic field applied along the easy axis induces a spin-fl…
Separation of the magnetic phases at the Néel point in the diluted spin-Peierls magnet CuGeO3
V. N. Glazkov, A. I. Smirnov, K. Uchinokura +1
The impurity induced antiferromagnetic ordering of the doped spin-Peierls magnet Cu(1-x)Mg(x)GeO(3) was studied by ESR technique. Crystals with the Mg concentration x<4% demonstrat…
Spin dynamics in the weakly-coupled chains antiferromagnet BaCuSiO
A. Zheludev, M. Kenzelmann, S. Raymond +3
Inelastic neutron scattering is used to identify single-particle and continuum spin excitations in the quasi-one-dimensional antiferromagnet \ba. In the data analysis, clos…
Zone-boundary excitations in coupled Haldane spin chain compounds PbNi2V2O8 and SrNi2V2O8
A. Zheludev, T. Masuda, K. Uchinokura +1
Magnetic excitations in the quasi-one-dimensional quantum antiferromagnets PbNi2V2O8 and SrNi2V2O8 are measured all the way up to the zone boundary energy using inelastic neutron s…
