Competition between axial anomaly and ferromagnetic ordering in Bi2-xFexSe3–xSx topological insulator: A study of magnetic and magnetotransport properties

Singh, Rahul; Kumar, Shiv; Jain A.; Singh, Mahima; Ghosh, Labanya; Singh A.; Banik, Soma; Lakhani A.; Patil S.; Schwier E.F.; Shimada K.; Yusuf S.M. (Chinese Ceramic Society, 2022-05)

The topological insulators Bi2-xFexSe3–xSx have been investigated by the dc-magnetization, magneto-transport and angle resolved photoemission spectroscopy (ARPES) techniques. With doping of Fe and S, a negative giant ...

Investigation of multi-mode spin–phonon coupling and local B-site disorder in Pr2CoFeO6 by Raman spectroscopy and correlation with its electronic structure by XPS and XAS studies

Pal, Arkadeb; Ghosh, Surajit; Joshi, Amish G.; Kumar, Shiv; Patil, Swapnil; Gupta, Prince K.; Singh, Prajyoti; Gangwar, V.K.; Prakash, P.; Singh, Ranjan K.; Schwier, Eike F.; Sawada, M.; Shimada, K.; Ghosh, A.K.; Das, Amitabh; Chatterjee, Sandip (Institute of Physics Publishing, 2019)

Electronic structure of Pr2CoFeO6 (at 300 K) was investigated by x-ray photoemission spectroscopy (XPS) and x-ray absorption spectroscopy techniques. All three cations, i.e. Pr, Co and Fe were found to be trivalent in ...
