Spin-accumulation in small ferromagnetic double barrier junctions
Arne Brataas, Yu. V. Nazarov, J. Inoue +1
The non-equilibrium spin accumulation in ferromagnetic double barrier junctions is shown to govern the transport in small structures. Transport properties of such systems are descr…
Electronic and magnetic states in doped LaCoO_3
K. Tsutsui, J. Inoue, S. Maekawa
The electronic and magnetic states in doped perovskite cobaltites, (La, Sr)CoO_3, are studied in the numerically exact diagonalization method on Co_2O_{11} clusters. For realistic…
Temperature-dependence of spin-polarized transport in ferromagnet / unconventional superconductor junctions
T. Hirai, Y. Tanaka, N. Yoshida +3
Tunneling conductance in ferromagnet / unconventional superconductor junctions is studied theoretically as a function of temperatures and spin-polarization in feromagnets. In d-wav…
Influence of impurity-scattering on tunneling conductance in d-wave superconductors with broken time reversal symmetry
N. Kitaura, H. Itoh, Y. Asano +4
Effects of impurity scattering on tunneling conductance in dirty normal-metal/insulator/superconductor junctions are studied based on the Kubo formula and the recursive Green funct…
Giant Orbital Hall Effect in Transition Metals: Origin of Large Spin and Anomalous Hall Effects
H. Kontani, T. Tanaka, D. S. Hirashima +2
In transition metals and their compounds, the orbital degrees of freedom gives rise to an orbital current, in addition to the ordinary spin and charge currents. We reveal that cons…
Parity-sensitive measurements based on ferromagnet/superconductor tunneling junctions
T. Hirai, N. Yoshida, Y. Tanaka +2
A method to identify the parity of unconventional superconductors is proposed based on tunneling spectroscopy. For a model of calculation, we adopt a ferromagnet/superconductor (F/…
