摘要：
The energetics of magnetovolume and magnetodistortive fluctuations of ordered Fe,Pt is examined using the LMTO-ASA method. It is shown that in the vicinity of low-volume nonmagnetic metastable state, distortive modes occur in the thermal range. We also discuss the Bain deformation path from the FCC to the BCC structure.
