- The effects of the spin degree of freedom of the free carriers in a solid material often get masked by the large classical electromagnetic interaction on its charge and also due to ?relaxation? effect that makes spin current non conservative. With the recent advancement in nanotechnology and ultra fast measurement techniques, it is now possible to design novel experimental schemes to overcome these challenges. This has led to a very active multidisciplinary field of research that aims at understanding the fundamentals of the spin dependent transport phenomenon that can eventually find application in the form of ?spintronic? devices. Our group explores wide range of materials that may have potential for spintronic applications due to longer spin coherence lengths and spin-orbit interaction. Currently we are investigating new classes of radical based organic semiconductors and topological insulators for quantum effects in transport properties using our low temperature and high magnetic field facility. Subsequently we aim to use these materials to focus on several challenging projects like electrical detection of spin hall effect, detection of spin currents using superconductive and ferromagnetic interfaces and manipulation of nanomagnets using spin torque. We have developed state-of-the -art facilities for synthesis of the thin films and multilayer samples and fabrication of nano and micro devices.
