Linear spin wave spectra were measured as a function of the angle θ between the sample normal and the direction of the applied magnetic field at temperatures between 140 K and RT, in charge uncompensated thin garnet film having the composition Y Ca Ge Fe O and reduced in FeCl or annealed ...
These results suggest that in both, the FeAs-1111 and the FeAs-122- compounds, columnar defects induce non-magnetic small-angle intra-band scattering, which does not contribute to pair-breaking for s±-gap symmetry. Critical current densities. The small size of the crystals used in our study...
Rocking curves with full-width at half-maximum smaller than 0.015° and finite- thickness oscillations visible in low angle reflectivity curves and around the (002n) Bragg peaks (n = 1,2,3) indicate the high quality of the films and interfaces. From the finite thickness oscillations the...
