Research Abstract |
By using a magnetic interlayer coupling a magnetic resonance mode with over 20 GHz was realized and successfully excited by a direct injection of electric current. By developing a theory based on a Boltzmann's treatment of electron, we showed that a temperature gradient may cause a spin-current and non-equilibrium spin-wave distribution may result in a large Seebeck coefficient. In addition, we showed an equation to evaluate energy dissipation in a diffusive spin-current. We showed that the tunneling magneto-resistive device may show a superior diode sensitivity compared with the semiconductor diodes.
