Magneto-optical Imaging Setup
Magneto-optical Imaging Setup
We use this for imaging local fields with a sensitivity of 10 mG in background fields of few 100 of Gauss. Currently the system operates between a 12 K to 300 K in a applied field upto 1 kG. Within the next couple of months we are looking forward to an upgrading this system to operate from much lower T and in magnetic fields of upto few tesla's.

Recently we have modified the above system to enable us to perform his sensitivity electric current distribution imaging. We use the above technique to image and map the self field generated by tiny electric currents sent across the sample, which inturn help us to construct a map of the local current distribution across any material (viz., superconductors, magnetic, topological insulators, semiconducting, metals). The adjoining figures are recent publications based on our current imaging
