摘要：
The present study reports the effect of swift heavy ion irradiation on structural and magnetic properties of sputtered Fe/W multilayer structure (MLS) having a bilayer composition of [W(30 angstrom)/Fe(20 angstrom)](10BL). The MLS was irradiated by 120 MeV Au9+ ions up to fluence of 4x10(13) ions/cm(2). Structural study of pristine and irradiated MLS reveals that intra-layer microstructure of Fe-layers in the MLS becomes nano-crystalline on irradiation. Magnetic studies show increase in coercivity at higher fluence which may be due to increase in surface and interface roughness after recrystallization of Fe-layers.
