【 摘 要 】

We measured magnetoresistance of the quadrupole ordered system PrV2Al20with a Γ3doublet ground state under high-DC magnetic field up to 30 T. The field dependence of the magnetoresistance is strongly different between H[111] and H[110] in spite of the cubic crystal structure. For H[110], we observed a jump with distinct hysteresis between 13 and 16 T and a shoulder structure in the field of 8 T at 23 mK.
