| Research Abstract |
Using ab-initio calculations for Co_2MnZ(Z=Na-S), Ni_2MnAl, and Ru_2MnSi with and without defects, we discussed how to understand the discrepancies between the band calculation and experimental results. We also examined the accuracy of our cluster expansion for total energies.
