  • Electronic structure by X-ray absorption spectroscopy and observation of field induced unusually slow spin relaxation from magnetic properties in pyrochlore 
    Pal, A.; Ghosh, S.; Kumar, S.; Schwier, E.F.; Sawada, M.; Shimada, K.; Gupta, M.; Phase, D.M.; Ghosh, A.K.; Chatterjee, S. (Elsevier B.V., 2019-04-15)
    X-ray absorption spectroscopy (XAS) and magnetization of hybrid pyrochlore Eu2-xFexTi2O7 (EFTO) were investigated, where the rare earth Eu (4f) was replaced with transition metal Fe (3d) to introduce competing 4f-3d ...
  • Existence of exchange bias and Griffith phase in (Tb1-xCex)MnO3 
    Ghosh, S.; Kumar, A.; Pal, A.; Singh, P.; Gupta, P.; Anand, K.; Gautam, U.K.; Ghosh, A.K.; Chatterjee, S. (Elsevier B.V., 2020-04-15)
    The structural and magnetic properties of (Tb1-xCex)MnO3 have been investigated. The presence of Griffith's phase has been confirmed from the AC susceptibility study of the materials. The observed Griffith phase in ...
  • 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 ...
  • 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. ...
  • Spin freezing and field induced transition in (Tb1−xEux)2Ti2O7: A magnetic property study 
    Singh, P.; Pal, A.; Gangwar, V.K.; Ghosh, S.; Singh, R.K.; Ghosh, A.K.; Chatterjee, S. (Elsevier B.V., 2020-11-15)
    The magnetic properties and Raman effect of (Tb1−xEux)2Ti2O7 have been investigated. Raman study indicates the existence of hardening due to phonon-phonon anharmonic interaction. The DC magnetic study indicates the significant ...
