1. 1. Hybrid Superconductor/Ferromagnet junctions with a strongly ferromagnetic barrier

   Författare :Olena Kapran; Vladimir Krasnov; Thilo Bauch; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Superconductivity; Josephson junctions; planar Josephson junctions; micro nanoscale fabrication; micromagnetic state; in-situ characterization technique; fysik; Physics;

   Sammanfattning : The spin-triplet superconducting state, predicted in superconductor /ferromagnet heterostructures remains one of the most exotic states of nature. It is expected that the triplet state can be switched on/off by changing the relative orientation of magnetization in multilayer Josephson spin-valve structures. LÄS MER

   Sammanfattning : This work concerns the microstructure of YBa2Cu3O7-.delta. (YBCO) and other related thin films in multilayer structures, studied by mainly transmission electron microscopy (TEM). LÄS MER

4. 3. Mesoscopic phenomena in hybrid superconductor/ferromagnet structures

   Författare :Taras Golod; Vladimir Krasnov; Alexandre Bouzdine; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Condensed matter physics; Kondenserade materiens fysik; fysik; Physics;

   Sammanfattning : This thesis explores peculiar effects of mesoscopic structures revealed at low temperatures. Three particular systems are studied experimentally: Ferromagnetic thin films made of diluted Pt1-xNix alloy, hybrid nanoscale Nb-Pt1-xNix-Nb Josephson junctions, and planar niobium Josephson junction with barrier layer made of Cu or Cu0.47Ni0.53 alloy.
