Abstract

The low temperature specific heats of nearly ferromagnetic NbFe₂ and TaFe₂ and antiferromagnetic TiFe₂ have been studied between 1.4 K and 6.5 K. The results are compared with the recent band calculations. It is shown that the electronic specific heat coefficients, γ, of NbFe₂ and TaFe₂ are significantly enhanced. The enhancement of γ of NbFe₂ is discussed in terms of the spin fluctuation theory.
