Vortex lattice dynamics in Nb films with competing intrinsic random and artificial periodic pinning

Mostrar todas las versiones(2)

We study vortex lattice (VL) dynamics in patterned Nb films containing dense periodic arrays of sub 50nm magnetic nanodots or holes, by means of ac susceptibility measurements. For both types of samples, we observe matching effects within a wide temperature range, determined by the periodicity of th...
