To clarify cation nonstoichiometry in Y123, Y123 sintered bulks and Y123 thin films starting from various yttrium compositions were synthesized. These samples were annealed under moderately high PO2 to promote yttrium substitution for barium-site. Y1

We report on femtosecond optical pump-probe studies of proximized ferromagnet/superconductor (F/S) hybrids, consisting of Ni0.5Cu0.5 layers deposited on top of Nb films. The weak ferromagnetic nature of the completely proximised Ni0.5Cu0.5 film makes

In this study, the angular dependence of Jc is investigated in detail for YBa2Cu3Oy (YBCO) tape fabricated by the inclined substrate deposition method. The result shows that Jc has a notable peak when the magnetic field is perpendicular to the plane
