A single-crystal study on the low-temperature magnetism of a pyrochlore magnet Pr2Zr2O7 has been carried out. The temperature dependence of the magnetic susceptibility shows no magnetic ordering at temperatures down to 1.9 K. The Curie-Weiss behavior was observed at temperatures below 10 K, yielding an effective moment µeff = 2.5µB. This result, combined with those of recent reports on other Pr3+ pyrochlore magnets, suggests that the ground state of the Pr3+ crystal electric field is a well-separated magnetic doublet. An anisotropic magnetization process is observed at lower temperatures, and the saturated magnetization values along the three high-symmetry directions are consistent with a local 〈111〉 Ising anisotropy with a magnetic moment g J J = µeff = 2.5µB.
