Abstract
The specific heat of C14 YMn2; YbMn2 and ThMn2 was measured in the tem perature range of 1.4 K to 10 K. The huge values of specific heat were observed for all compounds. The origin of the huge values of specific heat are considered to be derived from two mechanisms. For C14 YMn2 a nd ThMn2, those are ascribed to the excitations of large spin fluctuat ions of Mn moments. On the other hand, the extraordinary large value o f YbMn2 is due to the paramagnetic Yb moment.
