Giant longitudinal negative magneto-resistance under perpendicular magnetic field in BiFeSeS Topological insulators
Rahul Singh, Vinod K. Gangwar, Abhishek Singh +5
The magnetic, magneto-transport and ARPES studies of Fe and S co-doped Bi2Se3 were investigated. With doping concentration magneto-resistance (MR) gradually decreases and for a cer…

Room temperature large spontaneous exchange bias in hard-soft antiferromagnetic composite BiFeO3-TbMnO3
Prince Kr. Gupta, Surajit Ghosh, Shiv Kumar +12
We report the presence of giant spontaneous exchange bias (HSEB) in a hard and soft antiferromagnetic composite of BiFeO3-TbMnO3 (BFO-TMO in 7:3 and 8:2 ratio). The HSEB varies bet…
