We report the realization of a planar transverse domain wall (TDW) witharbitrary tilting angle in a magnetic biaxial nanowire under a transversemagnetic field (TMF) pulse with fixed strength and optimized orientationprofile. We smooth any twisting in azimuthal angle plane of a TDW and thuscompletely decouple the polar and azimuthal degrees of freedom. The analyticaldifferential equation that describes the polar angle distribution is thenderived and the resulting solution is not a Walker-ansatz form. With thisoptimized TMF pulse comoving, the field-driven dynamics of the planar TDW isinvestigated. It turns out the comoving TMF pulse increases the wall velocityunder the same axial driving field. These results will help to design a seriesof modern logic and memory nanodevices based on general planar TDWs.
