"Spin resonance in iron based superconductors"

Dr. Sudhakar Pandey, Department of Physics and Astronomy, University of Iowa

Abstract:

Superconductivity refers to a phenomenon in which some materials loose their electrical resistance completely when cooled below a critical temperature. The resistance-free state is called as the superconducting state.
In the superconducting state of some materials a resonance like feature appears in the spin excitation spectrum as observed using the neutron scattering experiments. This appearance of spin resonance provides important  informations about the microscopic origin of superconductivity. In this talk I shall discuss the spin resonance in context of the recently discovered superconductivity in several iron based materials.
