Synthesis and dc magnetic susceptibility of the diluted magnetic semiconducting Cd1−xMnxS nanocrystalline films

Nanocrystalline films of Cd1−xMnxS (0 ≤ x ≤ 0.5) with grain size of 36–58 nm were deposited on glass substrates at a substrate temperature of 300 K using resistive thermal evaporation. All the films exhibited wurtzite structure and the lattice parameters varied linearly with composition. The magnetic susceptibility increased sharply with Mn content ‘x’ and decreased with increase of the temperature.
