Anomalous Hall voltage rectification and quantized spin-wave excitation   induced by the simultaneous dc- and rf-current application in Ni81Fe19 wire
  An anomalous Hall effect and rectification of a Hall voltage are observed by applying a radio-frequency (rf) current through a single-layered ferromagnetic wire located on a coplanar waveguide. The components of the magnetization precession, both in and perpendicular to the plane, can be detected via the Hall voltage rectification of the rf current by incorporating an additional direct (dc) current. In this paper, we propose a phenomenological model, which describes the time-dependent anisotropic magnetoresistance and time-dependent planer Hall effect. The nonlinearity of the spin dynamics accompanied by spin-waves as functions of rf and dc currents is also studied, as well as those of the magnitude and orientation of the external magnetic field.
