Abstract

By properly choosing material parameters and geometry of a magnetic nanowire, pinned domain wall oscillations at a local constriction can be obtained at low current densities. The thickness modulation of the wire gives an additional uniaxial magnetic anisotropy, which modifies the transverse anisotropy energy that defines the critical current density required for the onset of domain wall oscillations. Broadband microwave signals are obtained with these values of current density.
