Specific heat measurements have been carried out in the short range spin correlated phase of the linear antiferromagnet (CH3)4NMnCl3 (TMMC) in order to ascertain effects due to dipolar interactions. The specific heat is linear in T at low temperatures as expected from spin wave theory. The measured coefficient is about one-third the isotropic spin-wave value, but is in better agreement with a prediction from anisotropic spin-wave theory (one-half the isotropic value).
