  A complexing molecule electrodeposition technique has been developed for the
deposition of low cost, lightweight MgB2 films, for the first time. Different
deposition parameters such as bath composition, deposition potential, current
density, deposition time were studied and optimized to give uniform,
homogeneous and sticky films. The MgB2 films were deposited at a constant
potential of -1.3 V with respect to Saturated Calomel Electrode (SCE) onto
silver substrate from aqueous bath and at -3.2 V with respect to SCE electrode
onto silver substrate from non-aqueous bath. XRD, SEM and EDAX techniques are
used to characterize these films. The films formed from non-aqueous
electrochemical bath show the superconducting transition temperature at Tc =
36.4 K. The method developed is of less energy inputs than any other existing
methods and of versatile nature having potential for large scale applications
of MgB2 superconductors. PACS numbers: 74.70.Ad, 81.15.Pq, 74.76.-w *Author for
