概要

• 論文の詳細を見る

• This letter reports preparation of γ-(Fe_<1-x>Os_x)_2O_3 thin films that have easy axis of magnetization normal to the film plane. This unusual condition was the result of magnetic annealing under an external field of 10 kOe perpendicular to the film plane. The optimum annealing temperature and Os content, x, to obtain film with a large perpendicular anisotropy were about 400℃ and 0.05, respectively. Read/write characteristic measurement of film with ring head exhibited a dipulse waveform, confirming perpendicular magnetic recording.
