Abstract
Superimposition of constant magnetic field (parallel and perpendicular) in Fe-Pd alloy electrodeposition shown interesting magnetic, morphological and microstructural properties of deposited thin films. X-ray diffraction results show a face centered cubic structure at (-1.0V and -1.05V ) and body centered cubic structure at (-1.1V ) based on anomalous co-deposition. Crystallite sizes (-1.05V (7.95nm)) are improving in presence of parallel external magnetic field (4.16nm), on the contrary perpendicular orientation increase the crystallite sizes (8.42nm). Field emission scanning electron microscopy images reveal densely packed uniform nanogranular nature of all films, where superimposition of parallel magnetic field leads to more finer grains. A clear soft ferromagnetic behavior with easy in-plane orientation found in all deposits. Increase in Fe (at%) in films leads to higher saturation magnetization. The highest saturation magnetization (Ms) is achieved (1157emu/cc(-1.1V ))in superimposed (k) magnetic field samples proves external magnetic field increases (Ms). Atomic force microscopy images reveal low film roughness (parallel field), whereas higher roughness are observed at (perpendicular field). Observed patch-like domains in magnetic force microscopy images at (-1.05V (k)) proves parallel magnetic field influencing domain formation. The counter play between external magnetic field and deposition potential to achieve high quality films in superimposed magnetic field electrodeposition were studied.
