Relations of crystal structure to magnetic properties in the quasi-one-dimensional compound PbNi1.88Mg0.12V 2O8 Mastoraki, I.; Lappas, A.; Giapintzakis, John; Többens, D.; Hernández-Velasco, J. (2004)The crystal structure of the quasi-one-dimensional oxide PbNi 1.88Mg0.12V2O8 has been studied by Rietveld analysis of combined high-resolution neutron and X-ray powder diffraction data at 300K and at low temperatures. The ...
Spin-gap and antiferromagnetic correlations in low-dimensional PbNi2-xAxV2O8 compounds (A = Mg, Co) Mastoraki, I.; Lappas, A.; Schneider, R.; Giapintzakis, John (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 ...
