Enhancement of pinning properties of superconducting thin films by graded pinning landscapes
M. Motta, F. Colauto, W. A. Ortiz +7
A graded distribution of pinning centers (antidots) in superconducting MoGe thin films has been investigated by magnetization and magneto-optical imaging. The pinning landscape has…
Domain-wall and reverse-domain superconducting states of a Pb thin-film bridge on a ferromagnetic BaFe_{12}O_{19} single crystal
R. Werner, A. Yu. Aladyshkin, S. Guenon +5
We report on imaging of the nonuniform superconducting states in a Pb thin film bridge on top of a ferromagnetic BaFe_{12}O_{19} single crystal with a single straight domain wall a…
Crossover between different regimes of inhomogeneous superconductivity in planar superconductor-ferromagnet hybrids
A. Yu. Aladyshkin, J. Fritzsche, R. Werner +5
We studied experimentally the effect of a stripe-like domain structure in a ferromagnetic BaFe_{12}O_{19} substrate on the magnetoresistance of a superconducting Pb microbridge. Th…
Direct visualization of magnetic vortex pinning in superconductors
M. Menghini, R. B. G. Kramer, A. V. Silhanek +6
We study the vortex structure in a Pb film deposited on top of a periodic array of ferromagnetic square microrings by combining two high resolution imaging techniques: Bitter decor…
Highly transparent superconducting - normal junctions in a homogeneous superconductor induced by local fields of magnetic domains
J. Fritzsche, R. B. G. Kramer, V. V. Moshchalkov
Using the highly inhomogeneous fields of a magnetic substrate, tunable junctions between superconducting and normal state regions were created inside a thin film superconductor. Th…
