• Development of niobium-based superconducting junctions 

  Nevala, Minna (University of Jyväskylä, 2012)

  This thesis presents a review of publications which mainly focuses on the fabrication and performance of Nb-based normal metal-insulator-superconductor (NIS) tunnel junctions and superconductor-normal metal-superconductor ...

• Charge transport through spin-polarized tunnel junction between two spin-split superconductors 

  Rouco, Mikel; Chakraborty, Subrata; Aikebaier, Faluke; Golovach, Vitaly N.; Strambini, Elia; Moodera, Jagadeesh S.; Giazotto, Francesco; Heikkilä, Tero T.; Bergeret, F. Sebastian (American Physical Society, 2019)

  We investigate transport properties of junctions between two spin-split superconductors linked by a spin-polarized tunneling barrier. The spin-splitting fields in the superconductors (S) are induced by adjacent ferromagnetic ...

• Thermodynamics of a Phase-Driven Proximity Josephson Junction 

  Vischi, Francesco; Carrega, Matteo; Braggio, Alessandro; Virtanen, Pauli; Giazotto, Francesco (MDPI, 2019)

  We study the thermodynamic properties of a superconductor/normal metal/superconductor Josephson junction in the short limit. Owing to the proximity effect, such a junction constitutes a thermodynamic system where phase ...

• Very Large Thermophase in Ferromagnetic Josephson Junctions 

  Giazotto, F.; Heikkilä, Tero; Bergeret, F.S. (American Physical Society, 2015)

  [Abstract.] The concept of thermophase refers to the appearance of a phase gradient inside a superconductor originating from the presence of an applied temperature bias across it. The resulting supercurrent flow may, in ...

• Superconducting tantalum nitride-based normal metal-insulator-superconductor tunnel junctions 

  Chaudhuri, Saumyadip; Maasilta, Ilari (American Institute of Physics, 2014)

  We report the development of superconducting tantalum nitride (TaN x ) normal metal-insulator-superconductor (NIS) tunnel junctions. For the insulating barrier, we used both AlO x and TaO x (Cu-AlO x -Al-TaN x and ...
