description |
Ratchet motion of superconducting vortices, which is a directional flow of
vortices in superconductors, is highly useful for exploring quantum phenomena
and developing superconducting devices, such as superconducting diode and
microwave antenna. However, because of the challenges in the quantitative
characterization of the dynamic motion of vortices, a phase diagram of the
vortex ratchet motion is still missing, especially in the superconductors with
low dimensional structures. Here we establish a quantitative phase diagram of
the vortex ratchet motion in a highly anisotropic superlattice superconductor,
(SnS)1.17NbS2, using nonreciprocal magnetotransport. The (SnS)1.17NbS2, which
possesses a layered atomic structure and noncentrosymmetry, exhibits
nonreciprocal magnetotransport in a magnetic field perpendicular and parallel
to the plane, which is considered a manifest of ratchet motion of
superconducting vortices. We demonstrated that the ratchet motion is responsive
to current excitation, magnetic field and thermal perturbation. Furthermore, we
extrapolated a giant nonreciprocal coefficient ({\gamma}), which quantitatively
describes the magnitude of the vortex ratchet motion, and eventually
established phase diagrams of the ratchet motion of the vortices with a
quantitative description. Last, we propose that the ratchet motion originates
from the coexistence of pancake vortices (PVs) and Josephson vortices (JVs).
The phase diagrams are desirable for controlling the vortex motion in
superlattice superconductors and developing next-generation energy-efficient
superconducting devices. |
