Abstract
Highly magnetic FeCo alloy films were deposited on Indium Tin Oxide (ITO) substrates by electrochemical deposition technique using different electrolytes. Synchrotron X-Ray Diffraction studies confirms the formation of pure FeCo films. The films deposited using different electrolytes results in varied morphology viz. flower-like and tilted nano-rod like structures. The magnetic studies of the films reveals that the rod-like structures shows single phase hysteresis loops with low coercivity ~155 Oe in the in-plane and ~337 Oe in the out of plane configuration. The higher coercivity in the out of plane configuration arising due to pinning effects is modelled by Monte-Carlo simulations to estimate the effective anisotropy constant. The domain configurations observed at various fields using Magneto Optic Kerr Effect Microscopy shows that the magnetization reversal process follows 180° domain motion. Such domain motion is a manifestation of higher stiffness constant as explained by the micromagnetic simulations.
