摘要：
Anomalies observed in the specific heat and magnetization of Er6Ni2Sn indicate magnetic phase transitions at 35, 17 and 7 K connected with various types of antiferromagnetic ordering below T-N (= 35). We report on specific-heat measurements of polycrystalline material in magnetic fields 0-14 T in the temperature range 3.5-150 X. From specific-heat data both, the total entropy change and the magnetocaloric effect have been evaluated for selected magnetic fields. Known magnetization data allowed us to calculate also the isothermal magnetic entropy change in fields up to 4 T and compared with values derived from the specific heat.
