Magnetic anisotropy in ferromagnetic Josephson junctions
arXiv:0805.3925 · doi:10.1063/1.2967873
Abstract
Magnetotransport measurements were done on $\Nb/\Al_2Ã_3/\Cu/\Ni/\Nb$ superconductor-insulator-ferromagnet-superconductor Josephson tunnel junctions. Depending on ferromagnetic $\Ni$ interlayer thickness and geometry the standard (1d) magnetic field dependence of critical current deviates from the text-book model for Josephson junctions. The results are qualitatively explained by a short Josephson junction model based on anisotropy and 2d remanent magnetization.
