  • Anomalous and topological Hall effect in Cu doped Sb2Te3topological insulator 
    Singh, A.; Gangwar, V.K.; Shahi, P.; Pal, D.; Singh, R.; Kumar, S.; Singh, S.; Gupta, S.K.; Kumar, S.K.; Kumar, S.; Cheng, J. (American Institute of Physics Inc., 2020-08-31)
    The magneto-transport and magnetization measurements of Sb1.90Cu0.10Te3 were performed by varying both temperature and the magnetic field. The induced antiferromagnetic ordering with Cu doping and the observed quantum ...
  • 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 ...
  • Room temperature exchange bias in antiferromagnetic composite BiFeO3-TbMnO3 
    Gupta, P.K.; Ghosh, S.; Kumar, S.; Pal, A.; Singh, P.; Alam, M.; Singh, A.; Roy, S.; Singh, R.; Singh, B.P.; Naveen kumar, N.; Schwier, E.F.; Sawada, M.; Matsumura, T.; Shimada, K.; Lin, H.-J.; Chin, Y.-Y.; Ghosh, A.K.; Chatterjee, S. (American Institute of Physics Inc., 2019-12-28)
    The magnetic property of a 0.7BiFeO3-0.3TbMnO3 composite has been studied in detail and compared with that of 0.8BiFeO3-0.2TbMnO3. The magnetic properties in 0.7BiFeO3-0.3TbMnO3 are improved in manifold compared to BiFeO3. ...
  • Smap soil moisture product assessment over wales, u.K., using observations from the wsmn ground monitoring network 
    Gupta, D.K.; Srivastava, P.K.; Singh, A.; Petropoulos, G.P.; Stathopoulos, N.; Prasad, R. (MDPI AG, 2021-06-01)
    Soil moisture (SM) is the primary variable regulating the soil temperature (ST) differences between daytime and night-time, providing protection to crop rooting systems against sharp and sudden changes. It also has a number ...
