We analyze the vortex core structure in the stripe phase of underdoped layered superconductors. The stripes arise primarily from charge-spin separation in a low-dimensional system. Coexistence of charge (hole-rich) and spin (hole-poor) nanodomains and superconductivity has been reported in recent years. Recently, the local density of states modulation around a vortex core has been found. The modulation indicates a competing type of order that can coexist with superconductivity. The idea is that where the superconducting order is suppressed in the core of a vortex, the competing order can be manifested. We analyze the competing orders on the basis of the Ginzburg-Landau theory. Finally, we note that the existence of competing orders gives rise to vortices that effectively have two core radii defined by the superconducting and charge coherence length.
