From: Controlling stable Bloch points with electric currents
Motion of a Bloch point in a nanostrip (\(l=600\,{\textrm{nm}}\), \(w=100\,{\textrm{nm}}\)) with a single notch under applied current. (a,b)Â Final configuration and Bloch-point trajectory for two different current strengths: (a)Â the Bloch point can move past the notch for \(J_x=1.6\times 10^{12}\,{\text {A/m}}{}^2\); (b)Â the Bloch point is trapped at the notch for \(J_x=1.4\times 10^{12}\,{\text {A/m}}{}^2\). (c)Â Simulated current profile. (d)Â Position of the Bloch points in (a) and (b) as a function of simulation time.
