Abstract

The specific heat of Sr14MnBi11 and Ba14MnBi11 was measured at temperatures between 2.8 K and 40 K. The low temperature specific heat is used to estimate the electronic and lattice contributions. The electronic constants, γ, are large suggesting that these two compounds are narrow-band metals with similar electronic structures. The Debye temperatures show that the bond strengths are about the same for the two materials. The ferromagnetic transition in Sr14MnBi11 is within the noise of the experiment but the antiferromagnetic transition in Ba14MnBi11 is clearly exhibited.
