The specific heat of C14 YMn2, YbMn2 and ThMn2 was measured in the temperature 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 and ThMn2, those are ascribed to the excitations of large spin fluctuations of Mn moments. On the other hand, the extraordinary large value of YbMn2 is due to the paramagnetic Yb moment.
