Abstract

To investigate the magnetic performance of a hybrid structure of transition metals, we consider the Fe3 Pt/Fe system and examine the effects both of the tetragonal distortion of Ll2 type Fe3 Pt and the hybridization with bcc-Fe on the magnetic properties, using LMTO-ASA method in the framework of LSD. The magnetic moment of Fe3 Pt has a maximum stationary value of 8.85 µB/cell at [formula omitted]. The hypothetical structure of Fe20 Pt4 is supposed by combining Fe3 Pt of [formula omitted] and bcc-Fe lattice. It is predicted that the magnetization reaches 2.27 T with the magnetic anisotropy constant of 11 × 105 J/m3. With using the coherent rotation model for magnetization reversal process, we get maximum energy product (BH)max = 10.2 MJ/m3.
