Thermoelectric spin diffusion in a ferromagnetic metal
Moosa Hatami, Gerrit E. W. Bauer, Saburo Takahashi +1
We present a semiclassical theory of spin-diffusion in a ferromagnetic metal subject to a temperature gradient. Spin-flip scattering can generate pure thermal spin currents by shor…
Sign reversal of ac Josephson current in a ferromagnetic Josephson junction
S. Hikino, M. Mori, S. Takahashi +1
The ac Josephson effect in a ferromagnetic Josephson junction, which is composed of two superconductors separated by a ferromagnetic metal (FM), is studied by a tunneling Hamiltoni…
Nonlocal spin Hall effect and spin-orbit interaction in nonmagnetic metals
S. Takahashi, S. Maekawa
Spin Hall effect in a nonlocal spin-injection device is theoretically studied. Using a nonlocal spin-injection technique, a pure spin current is created in a nonmagnetic metal (N).…
Superconducting pi qubit with a ferromagnetic Josephson junction
T. Yamashita, K. Tanikawa, S. Takahashi +1
Solid-state qubits have the potential for the large-scale integration and for the flexibility of layout for quantum computing. However, their short decoherence time due to the coup…
Spin Injection and Detection in Magnetic Nanostructures
S. Takahashi, S. Maekawa
We study theoretically the spin transport in a nonmagnetic metal connected to ferromagnetic injector and detector electrodes. We derive a general expression for the spin accumulati…
Conductance Quantization and Magnetoresistance in Magnetic Point Contacts
Hiroshi Imamura, Nobuhiko Kobayashi, Saburo Takahashi +1
We theoretically study the electron transport through a magnetic point contact (PC) with special attention to the effect of an atomic scale domain wall (DW). The spin precession of…
