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…
3D Deep Learning with voxelized atomic configurations for modeling atomistic potentials in complex solid-solution alloys
Rahul Singh, Aayush Sharma, Onur Rauf Bingol +4
The need for advanced materials has led to the development of complex, multi-component alloys or solid-solution alloys. These materials have shown exceptional properties like stren…
Physics-aware Deep Generative Models for Creating Synthetic Microstructures
Rahul Singh, Viraj Shah, Balaji Pokuri +3
A key problem in computational material science deals with understanding the effect of material distribution (i.e., microstructure) on material performance. The challenge is to syn…
Coexistence of surface and bulk state and negative magnetoresistance in Sulfur doped Bi2Se3
Rahul Singh, Vinod K. Gangwar, D. D. Daga +6
The magneto-transport properties in Sulfur doped Bi2Se3 are investigated. The magnetoresistance (MR) decreases with increase of S content and finally for 7% (i.e. y=0.21) S doping…
