Abstract

In this work we report on swift heavy ion irradiation induced nano granular magnetic metallic Fe 5Si 3 silicide phase formation due to strong interfacial intermixing in Fe/Si bilayer samples. The bilayer samples have been irradiated with swift (100 MeV) heavy ( 56Fe 7+) ions having a fluence of 1 × 10 14 ions cm −2. It has been found that swift heavy ion causes strong irradiation induced interfacial intermixing and forms nano granular magnetic metallic Fe 5Si 3 silicide in Fe/Si bilayer samples, which shows strong uniform magnetic interaction and interacting magnetic particle behaviour at room temperature (RT).
