  An oscillographic study of the Hall voltage with an unpolarized alternating
current through a platinum sample revealed choral features of the Hall effect,
which clearly demonstrate the presence of the spin Hall effect in metals with a
noticeable spin-orbit interaction. It was confirmed that, as in the case of
direct current, the possibility of a spin-Hall effect is associated with the
presence of an imbalance of the spins and charges at the edges of the samples,
which is realized using their asymmetric geometry. In particular, it was found
that such chiral features of the nonequilibrium spin-Hall effect, such as
independence from the direction of the injection current and the direction of
the constant magnetic field, in the case of alternating current, make it
possible to obtain a double-frequency transverse voltage, which can be used as
a platform for creating spintronics devices.
