摘要: Abstract We report on dynamics of superconducting vortices driven by a radial current in Corbino disk, where the rotate around center sample feeling frustrated Lorentz force inversely proportional to radius. Based mode-locking resonance, we have revealed formation rotating vortex rings composed triangular-lattice arrays. Both at high (4.1 K) and low (2.1 K) temperatures, observed change lattice orientation with respect flow direction under decreasing field.
