Abstract

The magnetic properties of the mixed compounds (Cox Ni1-x) 3 V2 O8 (CNVO) investigated by magnetization and neutron diffraction measurements are presented. Unlike their parent compounds Ni3 V2 O8 (NVO) and Co3 V2 O8 (CVO), only one magnetic phase transition into an antiferromagnetic phase was detected for powder samples with x=0.27, 0.52, and 0.76. The magnetic structures are modulated according to a propagation vector k =(δ,0,0) with δ being dependent on the composition parameter x. Furthermore, magnetization data of a CVO single crystal is featured, which is qualitatively different from previous publications and exhibits a controversial aspect concerning the behavior of the curve under an applied magnetic field along the b axis.
