9. The results of the Co were calculated by the linearized muffin-tin orbital method which is the linearized version of the KKR method. Strictly speaking, there is a difference between them. However, we compare the total energy difference between the P and AP spin configurations, so that the numerical errors with the both band calculations are expected to cancel out. Thus, it can be considered that it is possible to discuss the exchange coupling between the grains of the F Co and the AF NiMn.
