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.
