Magnetic switching of phase-slip dissipation in NbSe 2 nanoribbons

The stability of the superconducting dissipationless and resistive states in single-crystalline ${\mathrm{NbSe}}_{2}$ nanoribbons is characterized by transport measurements in an external magnetic field $(\mathbf{H})$. Current-driven electrical measurements show voltage steps, indicating the nucleation of phase-slip structures. Well below the critical temperature, the position of the voltage steps exhibits a sharp, periodic dependence as a function of $\mathbf{H}$. This phenomenon is discussed in the context of two possible mechanisms: the interference of the order parameter and the periodic rearrangement of the vortex lattice within the nanoribbon.
