Magnetic, thermal and transport properties of NdMn2

Susceptibility, magnetisation, specific-heat, thermal expansion and electrical resistivity measurements have been performed on NdMn₂ between 1.5 K and room temperature. Discontinuities are observed in the susceptibility, magnetisation and resistivity and large anomalies in the specific heat and thermal expansion at T_N(=104 K). Additional anomalies are found at 7 K and around 20 K in the specific heat and thermal expansion. The results are shown to be compatible with the picture for this compound proposed by Ballou et al.
