Magnetic and structural properties of poly methyl methacrylate (PMMA)/Fe film

Poly methyl methacrylate (PMMA) is a bio friendly polymer which forms transparent film and is used mainly in optical applications. In the present work iron (Fe) a magnetic material has been incorporated in PMMA and the magnetic and structural properties of the resulting nanocomposite has been reported. PMMA film has been prepared by solution casting method on float glass substrate. Ion Beam sputtering method was used to sputter iron (Fe) onto PMMA to obtain Fe layer with nominal thickness of 5 nm. GIXRD pattern was recorded to study the structure of the nanocomposite film. GIXRD pattern reveals the presence of Fe nanoparticles with BCC phase. Magnetic behaviour of the film was studied by magneto optic Kerr effect (MOKE) which shows well defined hysteresis loop with a coercive field of 24.39 Oe indicating soft ferromagnetic behaviour.
