Abstract

We have investigated martensitic transformation in a highly ordered Fe ₃Pt by X-ray diffraction measurements. We found that a new type of FCT martensite phase appears in Fe₃Pt with degree of order S = 0.88. In this martensite phase, the tetragonality c/a of the martensite is approximately 1.005 at 10 K, being different from that of so far known FCT martensite phase with c/a < 1.
