In this work, we have carried out a detailed study of the structural and magnetic properties of RVxCr1−xO4 (RTb, Dy, Er, and Yb; x = 0.0, 0.3, 0.5, 0.7 and 1.0) compounds obtained by the co-precipitation method. X-ray diffraction data using Rietveld refinement shows that all samples present a single phase consistent with the zircon-type structure (I41/amd space group (No. 141)). The lattice parameter changes as a function of both V-concentration and the rare earth ion. The analyses on T-dependent magnetic susceptibility indicate that RCrO4 samples are ferromagnetic while RVxCr1−xO4 ones are antiferromagnetic for x = 0.7 and 1.0. The increase of magnetic transition temperatures from 3 K (RVO4) to 20 K (RCrO4) can be an indicator that the R–Cr magnetic interaction takes an important role in the magnetic properties in these compounds. Isothermal magnetization curves measured at T = 2 K for all samples reinforce the ferromagnetic character of RCrO4 samples once they present remanence, coercivity, and magnetization saturation. However, the fact that the expected gJJ value for the full multiplet is not reached for all samples must be associated with the crystal electric field on the rare earth ion.
