| Abstract: | Fe/Pt alloy has two kinds of structure: ordered Fe/Pt alloy which is fcc phase of face-centered-cubic and disordered Fe/Pt alloy which is fct phase of face-centered-tetragonal. Fcc phase Fe/Pt alloy is super paramagnetic. The fct phase Fe/Pt alloy is ferromagnetic materials with high permanent magnetism,which has excellent abrasive and corrosion resistance. So Fe/Pt nanocrystal permanent magnets have been used in the field of medical instrument and high density magnetic recording. Since it has some restriction in practice,many studies concentrate on nano-Fe/Pt films. This paper,based on the recent researches in this field,summarized the microstructure characteristics of Fe/Pt?preparation method?heat treatment and adulterate that effect magnetic performance. |
| Keywords: | Fe/Pt alloy magnetization thin films preparation method heat treatment doped chemical element |
