Abstract

The changes in structural and magnetic properties of FePt thin films due to the irradiation with high energy ions (Br^7+^ and Cl^2+^) were studied. From the hysteresis loops dominating in‐plane anisotropy is derived, however, the samples present a minor out‐of‐plane component. The structure and the magnetic properties of the films can be tuned by selecting the appropriate irradiation parameters (different ions, energies and fluencies). For the irradiation parameters used in this study an in‐plane anisotropy is favoured. Irradiation with Br^7+^ seems to induce minor changes in the structural ordering of the thin films, whereas the Cl^2+^ ions promote the amorphization of the surface of the films. In addition, a magnetic thin film patterned at the micrometer scale was obtained after irradiation through a micrometric mask. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

## Abstract Microstructure, crystal structure, and magnetic properties of the Fe~49–x~Co~x~Pt~51~ (x = 0, 0.7, 1.3, 2.2) thin films deposited on glass substrates were investigated. The addition of Co was found to enhance the magnetization of the FePt __L__ l~0~ phase, thus increases the energy prod
