Abstract
We present the specific-heat study of the electronic properties of NpIrSn and NpNiSn, crystallizing in the ZrNiAl-type hexagonal and TiNiSi-type orthorhombic structure, respectively. NpIrSn orders antiferromagnetically below TN=38 K and undergoes a further magnetic phase transition at T1=23.5 K. The γ-coefficient of the electronic specific heat is only moderately enhanced to 75 mJ molâ1 Kâ2. ThIrSn, crystallizing in the same structure, is used to estimate the lattice specific heat to analyze the magnetic part. NpNiSn orders antiferromagnetically below TN=35.5 K. In both compounds the antiferromagnetic order is not affected by magnetic fields up to 14 T.
