Abstract

We report on the anisotropy of magnetization, electrical resistivity and upper critical magnetic fields (H(c2)) of U-GAMMA-d2Al3. The magnetization curve in the antiferromagnetically ordered state shows large anisotropy, indicating that the sublattice moments lie in the basal hexagonal plane. The value of -(dH(C2)/dT) at T(C) is estimated to be about 36 (kOe/K) for the magnetic field parallel and perpendicular to the hexagonal c-axis, and the upper critical field seems to be rather isotropic.
