| 内容記述 | 30 keV Kr+ ions were irradiated onto L12 ordered CrPt3 (20 nm) alloy films fabricated by a magnetron sputtering deposition followed by an appropriate heat treatment, and the modification of the structure and magnetic properties of the CrPt3 films was investigated in detail. The fabricated L12 CrPt3 (20 nm) onto a fused quartz substrate exhibited a quite large perpendicular anisotropy of 5×10^6 ergs/cc, due to the large lattice distortion of 1%. The large perpendicular anisotropy decreased with increasing the ion dose, and became almost zero at the ion dose of 2×10^14 ions/cm^2 due to the loss of the magnetic order of CrPt3. The suppression of the magnetic order of CrPt3 by the Kr+ ion irradiation is attributed to the transformation of the structure from the L12 phase to a disordered fcc phase, which was confirmed by x-ray diffraction analysis. Unlike the magnetization and perpendicular anisotropy, the anisotropy field of CrPt3 does not decrease significantly with the increase in the Kr+ ion dose, and exhibited more than 20 kOe even at the ion dose of 1×10^14 ions/cm^2. This is considered to be attributed that the lattice distortion of CrPt3 unchanged even at the Kr+ ion dose of 2×10^14 ions/cm^2. | |||||
