The low temperature specific heats of neodymium dihydride, NdH2.00, were measured in the temperature range 1.8 to 22K. A sharp λ-type specific heat anomaly due to a ferromagnetic transition has been found at Tc = (6.2 ± 0.1)K. The entropy change due to the magnetic contributions to the specific heat has been evaluated and interpreted.
