With the help of an artificially created spin imbalance that induces a charge imbalance unrelated to the Lorentz force, the relativistic spin-Hall effect (SHE) in 3D superpure monocrystalline aluminum was first studied. The nonlinear behavior of SHE in a magnetic field is revealed as a direct proof of the manifestation of the intrinsic (band) mechanism of the spin polarization of electrons in a nonmagnetic metal under spin-orbit interaction conditions with a minimized external impurity spin-polarization factor. Based on the data obtained, the spin-orbit coupling coefficient in aluminum is estimated.
