"Interplay between structure, magnetism and superconductivity in unconventional superconductors studied by neutron scattering." Much research has gone about the microscopic properties of the many different unconventional superconductors with the aim of finding the mechanism that binds (Cooper) pairs of electrons together, in turn forming the basis for the emergence of the superconducting state. In addition, to form the Cooper pairs a dynamic interaction is searched for, similar to the (BCS) electron-phonon coupling mechanism known from conventional superconductivity. A method to study lattice- and magnetic dynamics on the microscopic scale is neutron scattering, which is the central technique for this study. Two different two-dimensional superconductors will be studied using neutron scattering and other methods: The arch-typical cuprate (La,Sr)2CuO4 and the novel material LaPt2Si2; the latter of which does not a priory show microscopic magnetic properties.
