Abstract The magnetic properties of perovskite CaVO3 single crystals have been studied by means of magnetoresistance ρ (T, H) and magnetization M(H) measurements in fields to 18 T. At 2K, the magnetoresistance is positive and a maximum value of Δρ(18T)/ρ(0) = 16.5% is found for H//a. The magnetization exhibits a smooth increase at 2K, reaching values of M(18T) = 0.03μB (formula unit (fu))−1, 0.05,μB fu−1, 0.17/μB fu−1 for H//a, H//b and H//c, respectively. This anisotropy found in M(H) is consistent with that observed for Δρ(H//a) ≥ ρ(H//b) > Δρ(H//c). These results can be interpreted in terms of the field-dependent scattering mechanism of CaVO3.
