Notes:
New routes using laser and ion beam techniques are developed to synthesize iron oxide based magnetic materials. The first method, pulsed ruby laser treatment (pulse duration 30 ns, λ=0.694 μm) of thermally grown iron oxide (α-Fe2O3) under water, is shown to lead to the formation of FeO and Fe3O4 phases depending upon the choice of the treatment parameters. The other method, ion beam mixing to atomically mix a deposited overlayer of cobalt (400 A(ring) thick) on an α-Fe2O3 substrate with 100-keV Ar+ at a dose higher than 1×1016 ions/cm2, leads to ferrite formation. The surface layer sensitive technique of conversion electron Mössbauer spectroscopy (CEMS) was employed for characterization.
