Opis:: We report on the growth, structural and magnetic characterization of Nd$\text{}_{0.81}$Sr$\text{}_{0.19}$MnO$\text{}_{3}$/YBa$\text{}_{2}$Cu$\text{}_{3}$O$\text{}_{7}$ (NSMO/YBCO) superlattices. The NSMO system for the doping level of x=0.19 is a ferromagnetic insulator. Multilayers with a fixed NSMO thickness of 13 unit cells and a varying YBCO layer thickness from 2 unit cells to 6 unit cells were sputtered on LaAlO$\text{}_{3}$ substrates. An onset of superconducting transition is seen starting from the multilayer with 3 unit cells of YBCO layer thickness. Hysteresis loops recorded above and below the superconducting transition show a signature of interlayer exchange coupling.

Opis:: We report the synthesis and characterization of Nd$\text{}_{0.5}$Sr$\text{}_{0.5}$MnO$\text{}_{3}$/YBa$\text{}_{2}$Cu$\text{}_{3}$O$\text{}_{7}$ superlattices. X-ray diffraction studies show that the superlattices are [001] oriented. We observe that the magnetic ground state of Nd$\text{}_{0.5}$Sr$\text{}_{0.5}$MnO$\text{}_{3}$ system in a multilayered structure is strongly dependent on the substrate.

Opis:: Bilayered epitaxial $BiFeO_3$/$YBa_2Cu_3O_7$ films were fabricated on (100) $[(LaAlO_3)_{0.3}(Sr_2TaAlO_6)_{0.7}]$ substrates by sputtering method. For structural comparison the bilayered $BiFeO_3$/$La_{0.67}Sr_{0.33}MnO_3$ films were also deposited on (100) $SrTiO_3$ substrates. A weak ferromagnetic moment is observed in $BiFeO_3$/$YBa_2Cu_3O_7$ films. The mechanism responsible for weak ferromagnetic moment arises presumably from the epitaxy strain induced canted antiferromagnetic structure.

Opis:: Differential dynamical subgap transport measurements were performed on LSMO/YBCO/LSMO trilayers to probe local evolution of the Andreev bound states which are manifested as the zero bias conductance peak. Dynamical conductivity dI/dV vs. magnetic field measured in current in plane and current perpendicular to plane geometries show nonmonotonic behavior with maximum at about 500 Oe. The shape of the zero bias conductance peak measured in current in plane geometry is sharp, whereas zero bias conductance peak measured in current perpendicular to plane geometry demonstrates V shape. These shapes of the zero bias conductance peak were predicted theoretically for unconventional p-wave spin triplet phase superconductor and superconductor with d-wave symmetry of the order parameter, respectively.

Opis:: The magnetometry and the magnetic force microscopy are used to study the influence of the magnetic domain size on the flux pinning in a superconducting/ferromagnetic bilayer (SFB), in which the S layer is niobium and the F layer is a Co/Pd multilayer with perpendicular magnetic anisotropy. The domain size is pre-defined using the angle-dependent demagnetization. The enhancement of pinning is found to be the strongest, up to a factor of 6, for narrow domains and small magnetic fields. This result differs from the behavior observed in the SFB in which the F layer is Co/Pt. The difference may be attributed to the degree of the disorder in the domain pattern.
