The growth mechanism and morphology of MgB 2 films grown on magnesium films by electrocrystallization technique were discussed. The current time transients (CTT) recorded for charge transfer reaction during growth of MgB 2 films were used to infer the type (Instantaneous or Progressive) of growth me

In order to synthesize MgB 2 films, electrolysis is performed in an electrolyte comprising a fused mixture of B 2 O 3 , KCl and MgCl 2 in a molar ratio of B 2 O 3 :KCl:MgCl 2 = x:3.5:5. The results of the Meissner effects and X-ray diffraction measurements indicate the formation of MgB 2 films on gr
Superconductor MgB 2 thin films with thickness 200 nm were prepared on sapphire substrates by co-deposition of boron and magnesium. Precursor MgB thin films were deposited from two independent magnetron sources-boron by rf magnetron sputtering and magnesium by dc magnetron sputtering. MgB precursor
