Abstract: We have carried out specific heat measurements on EuIn2P2 at high magnetic fields perpendicular to the -axis in the hexagonal crystal structure in order to understand its thermal properties. The temperature dependence of the specific heat exhibits a clear -type anomaly due to a magnetic transition at , indicating that the magnetic transition is of second-order. The -type anomaly becomes markedly broader with increasing the magnetic field. This remarkable field-dependence is consistent with the results of previous magnetization measurements which suggest that magnetic moments align ferromagnetically perpendicular to the -axis below . In addition, a hump in the specific heat is observed around 7K, which can be ascribed to the Zeeman splitting of the multiplet by internal magnetic fields. [Copyright &y& Elsevier]
