| 英文摘要 | We have epitaxially deposited FeGa films onto MgO(001) substrates at an oblique angle phi varying from 0 degrees to 45 degrees and systematically investigated their magnetization reversal. The square and two-step hysteresis loops were observed in the samples deposited at phi = 0 degrees and 15 degrees. The reversed two-step and three-step hysteresis loops were observed in the samples deposited at phi = 30 degrees and 45 degrees, in which a strong uniaxial magnetic anisotropy K-u was induced by the oblique deposition. A model based on domain wall (DW) nucleation and propagation was employed to quantitatively describe the angular-dependent behaviors of FeGa epitaxial films, which indicates that, for the samples deposited with increasing phi, the 180 degrees magnetic transitions occurring in the magnetic field orientation between -45 degrees and 45 degrees gradually change from the two successive 90 degrees DW nucleations to the 180 degrees DW nucleation. |
