Nanostructured Cd(1-x)Mn(x)S films for spintronics and optoelectronic device applications: synthesis and characterization.

Nanostructured Cd(1-x )Mn(x)S (x = 0.3 and 0.4) films were prepared on glass substrates by thermal evaporation. All the films were deposited at 373 K and annealed at 473 K in high vacuum of 2 x 10(-6) mbar. The nanostructure films were characterized for composition, structure, morphology, optical and magnetic properties. All the films exhibited wurtzite structure of the host CdS material. AFM studies showed that all the films were in nanocrystalline form with the grain size varying in the range of 25-43 nm. The magnetic susceptibility increased sharply with Mn content 'x'.
