It is shown that the saturation current Js is decreased (increased) in the case of the codirected (oppositely directed) magnetic field and the current. There exists a critical current Jc > Js; which provides a “rigid” saturation – the saturated state is stable with respect to the transverse magnetic field of any amplitude and direction. The influence of a magnetic field on the vortex-antivortex crystals, which appear in a pre-saturated regime, is studied numerically. All analytical results are verified using micromagnetic simulations. |
