Interface, volume, and thermal attenuation of hot-electron spins in Ni80Fe20 and Co.
The relative importance of interface, volume, and thermal scattering in spin-dependent hot-electron transmission of magnetic trilayers is quantified. While interfaces produce significant attenuation (factor 2.2 per interface), the spin asymmetry is dominated by volume scattering. Extracted thermal attenuation lengths (130 A at 300 K for Ni80Fe20) show that thermal spin-wave scattering is strong...
متن کاملPhoton and electron spins.
It is easy to draw an intuitive parallel between the classical free electromagnetic field and its corresponding quantum, the photon-a spin-1 object. The situation with a massive particle such as an electron is less clear, as a real-world analog of the classical field whose quantum is the massive particle is not available. It is concluded that the fermion particle perspective provides the best a...

متن کاملAnisotropic spin-orbit scattering of hot-electron spins injected into ferromagnetic thin-films.
Anisotropic spin-orbit scattering of hot-electron spins in ferromagnets is examined by injecting a hot-electron current into the thin ferromagnetic base of a transistor and measuring the current attenuation as a function of the magnetization orientation. The transmission anisotropy is described by a simple model, from which we extract an effective spin-orbit scattering length of 420 nm for hot-...
متن کاملThe electron cyclotron maser in hot thermal plasmas
We investigate the possibility of an electron cyclotron maser operating in a hot (T > 107K) thermal plasma with a loss cone. We find that the instability can occur in this scenario because resonance involving electrons in the thermal tail can give rise to significantly large growth rates. We estimate the range of electron velocities that can be in resonance and show how this dictates the freque...
