Unraveling the temperature-dependent spin-polarized electron transport in iron via spin-wave Doppler shift
The electric current in epitaxial iron is highly spin-polarized (80%). This is determined by measuring the Doppler shift this current produces on spin waves as function of the temperature. Here, the authors then propose a resistivity model in which electron scattering with phonons, magnons and film interfaces give rise to such large polarization. These results provide a new experimental observable to understand the nontrivial many-body physics of spin-polarized electron scattering in ferromagnetic materials.
