Query: The electrical resistance of spatially varied magnetic interface. The
  role of normal scattering   We investigate the diffusive electron transport in conductors with spatially
inhomogeneous magnetic properties taking into account both impurity and normal
scattering. It is found that the additional interface resistance that arises
due to the magnetic inhomogeneity depends essentially on their spatial
characteristics. The resistance is proportional to the spin flip time in the
case when the magnetic properties of the conducting system vary smoothly enough
along the sample. It can be used to direct experimental investigation of spin
flip processes. In the opposite case, when magnetic characteristics are varied
sharply, the additional resistance depends essentially on the difference of
magnetic properties of the sides far from the interface region. The resistance
increases as the frequency of the electron-electron scattering increases. We
consider also two types of smooth interfaces: (i) between fully spin-polarized
magnetics and usual magnetic (or non-magnetic) conductors, and (ii) between two
fully oppositely polarized magnetic conductors. It is shown that the interface
resistance is very sensitive to appearing of the fully spin-polarized state
under the applied external field.
