We request funding to extend our current SNF program for one year in order to finish the thesis of our two Ph.D. students, Nikola Egetenmeyer and Simon Gerber. Their thesis topic is “Interplay of magnetism and superconductivity in selected unconventional superconductors”. The main experimental techniques of our research are neutron scattering with: triple-axis, small angle scattering, SANS, powder and single-crystal diffraction instruments. In selected cases we, furthermore, perform muon spin rotation, µSR, and angle-resolved photoemission spectroscopy, ARPES, measurements. The experiments are carried out at our institution, the Paul Scherrer Institut, PSI, Switzerland and at the Institut Laue Langevin, ILL, Grenoble, France. For the requested extension year we propose to complete the following projects: (i) Studies of subtle (but we believe important) features of the Q phase of CeCoIn5 by neutron diffraction. (ii) Development and implementation at PSI of a technique to study the vortex lattice, VL, of unconventional superconductors in an applied electrical current (iii) Study of the superconducting and normal state of Ca3Ir4Sn3, a newly discovered superconductor, by µSR and inelastic neutron scattering. (iv) Study of the VL of selected high-Tc cuprate superconductors using the SANS technique at very high fields, up to 17 T. (v) Study of the superconducting state of Ni doped BaFe2As2 by low- energy muons. For the above-mentioned experiments we have obtained high-quality single crystals, synthesized at PSI and abroad.
