  By numerically solving the Bogoliubov-de Gennes equations for the single
vortex state in a two-band superconductor, we demonstrate that the disparity
between the healing lengths of two contributing condensates is strongly
affected by the band Fermi velocities, even in the presence of the magnetic
field and far beyond the regime of nearly zero Josephson-like coupling between
bands. Changing the ratio of the band Fermi velocities alters the temperature
dependence of the condensate lengths and significantly shifts parameters of the
``length-scales locking" regime at which the two characteristic lengths
approach one another.
