Magnetic properties of the NiAs-type MnAs in paramagnetic and ferromagnetic phases are studied on the basis of the spin fluctuation theory. For use in this calculation we have calculated the electronic bands by the self-consistent APW method. The results for the magnetic susceptibility and magnetic moment are found to be consistent with observations. In particular, the anomalous behavior of the susceptibility in the intermediate phase of the MnP-type structure is explained qualitatively.
