Mössbauer spectroscopy studies of oxypnictides superconductors

The contribution of Mössbauer spectroscopy to the study of conventional superconducting materials, Chevrel phases, rare earth rhodium borides, high Tc cuprates, and Ru-based superconducting-magnetic systems are very shortly reviewed. The newly discovered oxypnictides, magnetic and superconducting (mostly the Fe–As) systems, are discussed in great detail.
