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