Research


Dr. Subhash's research aims to unveil the relevant correlations that control the physics in the strongly correlated regime and to develop few new spinel cubic phase nanostructures useful for microwave devices. Understanding the physics of strongly correlated electron systems is one of the most fascinating and difficult problems in condensed matter physics. In a recent work, he addressed the origin of re-entrant spin-glass behavior and complex magnetic properties of the few ferrimagnetic spinels like Mn3O4 and Co2SnO4.h-index 16, i10-index 27

Dr. Subhash's research also focuses on the synthesis and characterization of Nanostructured Magnetic Materials, High-k dielectrics and Relaxor-ferroelectrics. In a latest report, he demonstrated the origin of relaxor like behavior in Dy2O3 doped KNaNbO3 ceramics and Zn1-xNixO/NiO two-phase.

Spintronic Materials - Interlayer coupling in multilayers, Magneto-transport properties, Multiferroics, and Half metals
