Disorder-induced vortex phase transition in untwinned YBa2Cu3O7-δ crystal
(2000)Local magnetic measurements in an untwinned YBa2Cu3O7-δ crystal as a function of temperature, field and time reveal anomalies occurring along the same line BSS(T) in the field-temperature plane. We identify BSS(T) as a ...

Sign reversal of the Hall effect in YBa2(Cu1-x)3O7-δ single crystals
(1995)We have measured the in-plane Hall effect and in-plane resistivity of cobalt-doped YBa2Cu3O7-δ (YBCO) single-crystal samples. The concentration of cobalt ranged from 1 to 3%. As the applied field was varied, a sign reversal ...

Spin-gap and antiferromagnetic correlations in low-dimensional PbNi2-xAxV2O8 compounds (A = Mg, Co)
(2002)The effect of the impurity doping in the quantum-spin chains of the PbNi2V2O8 Haldane-gap compound is studied. We report elastic neutron scattering and bulk magnetic susceptibility measurements on the quasi-one-dimensional ...
