Hysteretic vortex pinning in superconductor-ferromagnet nanocomposites

This Letter reports the observation of hysteresis in the vortex pinning in a superconductor-ferromagnetic epitaxial nanocomposite consisting of fcc Gd particles incorporated in a Nb matrix. We show that this hysteretic pinning is associated with magnetic reversal losses in the Gd particles and is fundamentally different in origin to pinning interactions previously observed for ferromagnetic particles or other microstructural features.     

Influence of the dopant concentration in In-doped SrTiO3 on the structural and transport properties

thin films are grown epitaxially on NdGaO₃ (001) and characterized for x=0, 0.005, 0.02, 0.1, 0.2, 0.5. While films with x=0, 0.2 and 0.5 are insulating, the ones with x=0.005, 0.02 and 0.1 are semiconducting and show a p-type behaviour. Highly rectifying diodes composed of SrIn_0.005Ti_0.995O₃ grown on SrNb_0.02Ti_0.98O₃ thin films confirm this behavior. Therefore the use of In as a dopant in SrTiO₃ is promising in the field of semiconductors.
