Imaging the Spatial Distribution of Transport Currents and the Phenomenon of Nanoscale Phase Separation Phenomenon in CMR Materials
Abstract
The aim of the proposal was to develop a magneto-optics imaging "MOI" set up which will enable the direct imaging of transport current distribution inside a variety of materials. The primary objective of the proposal was to enhance the sensitivity of the existing magneto-optical imaging setup developed in the PI's laboratory to optically image the self fields generated by transport currents sent through materials. Based on the above objective it was planned to apply this technique to investigate fundamental issues like magnetic phase separation in colossal magneto resistive materials as well as to investigate possible applications like nondestructive detection of stress and fatigue in materials. As of now, success has been achieved in enhancing the sensitivity of our MOI setup so as to enable the imaging of transport currents down to 20 mAmps. Furthermore, characterization of the magnetic ground state in a particular CMR material has been performed, which subsequently will be investigated with the MOI setup.
