Ferromagnetism in cobalt doped n-GaN
S. Dhara, B. Sundaravel, K. G. M. Nair +5
Ferromagnetic ordering is reported in the post-annealed samples of Co doped n-GaN formed by Co+ implantation. A maximum Curie temperature ~ 250K is recorded for the sample with 8 a…

Blueshift of plasmon resonance with decreasing cluster size in Au nanoclusters embedded in silica matrix
S. Dhara, B. Sundaravel, T. R. Ravindran +3
Gold nanoclusters are grown by 1.8 MeV Au++ implantation in silica matrix and subsequent air annealing in the temperature range of 873K-1273K. Post-annealed samples show plasmon re…
