Superconductivity in Ca10(Ir4As8)(Fe2As2)5 with Square-Planar Coordination of Iridium
Kazutaka Kudo, Daisuke Mitsuoka, Masaya Takasuga +10
We report the unprecedented square-planar coordination of iridium in the iron iridium arsenide Ca10(Ir4As8)(Fe2As2)5. This material experiences superconductivity at 16 K. X-ray pho…
UPt as a Topological Crystalline Superconductor
Yasumasa Tsutsumi, Masaki Ishikawa, Takuto Kawakami +4
We investigate the topological aspect of the spin-triplet -wave superconductor UPt through microscopic calculations of edge- and vortex-bound states based on the quasiclassi…
Transverse magnetic field and chiral-nonchiral transition in vortex states for nearly B//ab in chiral p-wave superconductors
Masahiro Ishihara, Yuujirou Amano, Masanori Ichioka +1
On the basis of Eilenberger theory, we study the vortex state when a magnetic field is applied nearly parallel to the ab plane in a chiral p-wave superconductor with a large anisot…
Rotation of Triangular Vortex Lattice in the Two-Band Superconductor MgB2
Tomoya Hirano, Kenta Takamori, Masanori Ichioka +1
To identify the contributions of the multiband nature and the anisotropy of a microscopic electronic structure to a macroscopic vortex lattice morphology, we develop a method based…
Surface Bound States and Spontaneous Current in Cyclic d-Wave Superconductors
Masaki Ishikawa, Yasumasa Tsutsumi, Masanori Ichioka +1
On the basis of Eilenberger theory, surface bound states and spontaneous current are studied in cyclic d-wave superconductors as a broken time-reversal symmetry of superconductivit…
Anisotropy of the Superconducting State in Sr2RuO4
C. Rastovski, C. D. Dewhurst, W. J. Gannon +6
Despite intense studies the exact nature of the order parameter in superconducting Sr2RuO4 remains unresolved. We have used small-angle neutron scattering to study the vortex latti…
