Hierarchical nanofabrication and single crystal synthesis of solid state materials.
Prof. Singh's research is focused on understanding the microscopic mechanism behind magnetic and superconducting phenomena in strongly correlated electron systems in nanostructured and bulk forms. The group has developed novel nanofabrication scheme to create large throughput artificial magnetic lattice systems that are suitable for investigation using the macroscopic probes of polarized neutron reflectometry (PNR), neutron spin echo (NSE), small angle neutron scattering (SANS), primarily performed at SNS-ORNL, and X-ray photon correlation spectroscopy (XPCS). We also perform Hall probe measurements, besides the detailed investigation of electrical, magnetic and non-linear susceptibility, on the newly created materials.
Another aspect of his research involves the synthesis of crystalline materials of perovskite, geometrically frustrated systems and chalcogenides using solid state reaction and floating zone methods. Single crystal and polycrystalline samples are investigated using detailed neutron scattering methods of triple axis spectroscopy (TAS) and multi-axis crystal spectroscopy (MACS) at the NIST Center for Neutron Research, in addition to onsite characterizations of electrical, magnetic and ac susceptibility analysis.
