Talk on "Magnetic Nanostructure and its composites for Various Applications" by Prof. Neeraj Khare, Department of Physics, Indian Institute of Technology (IIT), New Delhi, on Tuesday, 17th April 2018 at SNU.

The scientific quest in the area of nanomagnetism is to

(i) synthesis magnetic nano-particles,                   

(ii) understand properties with reference to its bulk counterpart and

(iii) use it for applications.

The main challenge in the synthesis of magnetic nano-particle is to synthesize uniform size nano-particles with controlled magnetic properties. In our group at IIT Delhi, we have synthesised different nanostructure oxides and its nanocomposites, core-shell nanostructures and explored its potentiality for various applications. We have found that the presence of intrinsic strain induces cationic redistribution among the tetrahedral and octahedral sites in cobalt ferrite (CFO) which resulted in the change of the optical bandgap and saturation magnetization of the CFO nano-particles. One of the interesting applications of nano-magnetic particles is to use it for enhancing flux pinning in superconductors. Other interesting application is for the photocatalysis. The magnetic nano-particles can be used in conjunction with other semiconducting materials as core/shell or composite nanostructures for enhancing the photocatalytic activities. Another interesting application of nanostructure magnetic oxides have been explored for developing magnetically tunable microwave filters. This talk will review the progress achieved so far in the above mentioned area.
