AB  - We observed a remarkable improvement of domain wall (DW) mobility, DW velocity, 
      giant magnetoimpedance (GMI) effect and magnetic softening at appropriate 
      stress-annealing conditions. Beneficial effect of stress-annealing on GMI effect 
      and DW dynamics is associated with the induced transverse magnetic anisotropy. An 
      improvement of the circumferential permeability in the nearly surface area of 
      metallic nucleus is evidenced from observed magnetic softening and remarkable GMI 
      effect rising. We assumed that the outer domain shell with transverse magnetic 
      anisotropy associated to stress-annealing induced transverse magnetic anisotropy 
      affects the travelling DW in a similar way as application of transversal bias 
      magnetic field allowing enhancement the DW velocity. Observed decreasing of the 
      half-width of the EMF peak in stress-annealed microwires can be associated to the 
      decreasing of the characteristic DW width. Consequently, stress annealing enabled 
      us to design the magnetic anisotropy distribution beneficial for optimization of 
      either GMI effect or DW dynamics.
