30 keV Kr+ ion irradiation onto L12 ordered CrPt3 alloy film transforms the crystal structure of CrPt3 from L12 to A1 phases, which results in the change of magnetism from ferrimagnetism to paramagnetism. Bit patterned structure was fabricated by the local ion irradiation on CrPt3, and its magnetization reversal process was investigated by magnetic force microscope observations. The patterned CrPt3 bits with the size of 50 nm x 50 nm are considered to have a single domain state and their magnetization reversals undergo individual coherent rotations. With decreasing the bit size of the patterned CrPt3, the average switching field Hsf of the bits increased, while the switching field distribution ΔHsf decreased. This indicates that small ΔHsf / Hsf is possible for high density ion irradiated planar bit patterned media |
