Özet

We calculate in this work the specific heat C-VI using the predictions of an Ising model for the NH4Br crystal (T-C = 234 K, P = 0). Our calculated C-VI values are in good agreement with the experimentally observed C-p data from the literature. This shows that the observed behavior of NH4Br can be described adequately in the lattice region under an Ising model studied here.
