Penetration Depth of Transverse Spin Current in Ferromagnetic Metals
Tomohiro Taniguchi, Satoshi Yakata, Hiroshi Imamura +1
The line width of the ferromagnetic resonance (FMR) spectrum of Cu/CoFeB/Cu/Co/Cu is studied. Analyzing the FMR spectrum by the theory of spin pumping, we determined the penetratio…
Spin transport and relaxation in superconductors
T. Yamashita, S. Takahashi, H. Imamura +1
We study theoretically the effect of spin relaxation on the spin transport in a ferromagnet/superconductor(FM/SC) tunnel junction. When spin-polarized electrons are injected into t…
Joule heating generated by spin current through Josephson junctions
S. Takahashi, T. Yamashita, T. Koyama +2
We theoretically study the spin-polarized current flowing through a Josephson junction (JJ) in a spin injection device. When the spin-polarized current is injected from a ferromagn…
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…
Spin-Imbalance and Magnetoresistance in Ferromagnet/Superconductor/Ferromagnet Double Tunnel Junctions
S. Takahashi, H. Imamura, S. Maekawa
We theoretically study the spin-dependent transport in a ferromagnet/super- conductor/ferromagnet double tunnel junction. The tunneling current in the antiferromagnetic alignment o…
