The sample prepared by RTA at 550°C has (001) texture and strong magnetic perpendicular anisotropy with Hc equal to 6 kOe. The sample irradiated at 5.04 μA/cm2 has Hc equal to 10 kOe but has isotropic magnetic properties due to the (111) texture. The magnetic correlation length of the ion-irradiated sample was about twice as large as that of the RTA sample. This may be due to the inhomogeneity of the L10 phase formation in the ion-irradiated film., application/pdf}, pages = {10H306-1--10H306-3}, title = {Magnetic properties and L10 phase formation of FePt films prepared by high current-density ion-beam irradiation and rapid thermal annealing methods}, volume = {97}, year = {2005} }
