Abstract: The features of spin injection into a helicoidal ferromagnet are investigated. Two methods of spin injection are considered: injection of a spin-polarized current and spin pumping. For the case when the axis of the helicoid is perpendicular to the interface through which the spin injection occurs, the conditions are determined under which electrons fill the specified spin subband. For the case when the axis of the helicoid is parallel to the interface, the occurrence of an effect similar to the topological Hall effect is demonstrated. In the second geometry of spin pumping, we discovered the phenomenon of conversion of the injected spin current into an electric current, flowing along the axis of the helicoid, due to the exchange interaction in a ferromagnet.
Keywords: noncollinear ferromagnet, spin pumping, topological Hall effect, spin injection, exchange interaction.
