First Observed Metal-like to Insulator Transition in the vacant 3d orbital Quantum Spin Liquid TbTiO
B. Santhosh Kumar, C. Venkateswaran
We report the observation of metal-like to insulator transition (MTI) in the 3dpyrochlore oxide Tb2Ti2O7 at 603 K due to the interaction of empty 3d orbitals of Ti4+ with O2- ions,…

Crossover to negative dielectric constant in perovskite PrMnO3
Santhosh Kumar Balu, N. Praveen Shanker, M. Manikandan +4
Negative dielectric constant materials, once an incumbrance for physicists, are now the stockpiles of unique optical and microwave devices that will also avoid complex geometries.…
