Extraordinary magnetic properties of double perovskite Eu2CoMnO6wide band gap semiconductor

Alam, M.; Singh, P.; Anand, K.; Pal, A.; Ghosh, S.; Ghosh, A.K.; Singh, R.K.; Joshi, A.G.; Chatterjee, S. (Institute of Physics Publishing, 2020-08-26)

Some novel magnetic behaviours in double perovskite Eu2CoMnO6 (ECMO) have been reported. The x-ray photoemission spectroscopy study shows the presence of mixed valence states of transition metal ions. The UV-visible ...
Identification of point defects on Co-Ni codoping in SnO2 nanocrystals and their effect on the structural and optical properties

Roy, S.; Prajapati, B.; Singh, A.; Joshi, A.G.; Chatterjee, S.; Ghosh, A.K. (American Institute of Physics Inc., 2019-10-21)

Sn 0.97 - yCo 0.03Ni yO 2 (0 ≤ y ≤ 0.04) nanocrystals, with the average crystallite size in the range from 7.3 nm (for y = 0.00) to 5.6 nm (for y = 0.04), have been synthesized using a pH-controlled chemical coprecipitation ...
