N2 - We succeeded in growing a single crystal of NpSb 2 with the SmSb 2-type orthorhombic structure by the Sb-flux method and measured the electrical resistivity, specific heat, magnetic susceptibility and magnetization. NpSb 2 is found to be an Ising-type ferromagnet with the Curie temperature T C = 47 K, where the ordered moment of 1.6μ B/Np is oriented along the [001] direction. The electronic specific heat coefficient is estimated to be 22 mJ/(K 2·mol). The electrical resistivity for the current J ∥ [001] is by two orders of magnitude larger than that for J ⊥ [001], suggesting the quasi-two-dimensional electronic state.
