摘要：

Specific-heat measurements have been performed on the tetragonal ThMn12-type compounds NdFe4Al8, HoFe4Al8, ErFe4Al8 and YFe4Al8 in the temperature range 1.5-200 K. There are only very small anomalies associated with the magnetic ordering of the Fe sublattice in the high-temperature part of the specific-heat curves and with the magnetic ordering of Nd and Ho in the low-temperature part. A sharp peak in the specific heat, indicative of magnetic ordering of the Er moments at 5.5 K, is observed in ErFe4Al8. (C) 1998 Elsevier Science S.A. All rights reserved.
