  By considering Higgs modes within the Ginzburg-Landau framework, we study
influences of a rotated magnetic field on the color-flavor-locked-type matter
of dense QCD. We demonstrate, in a model-independent way, that a diquark
condensate may be triggered by the magnetic response of rotated-charged Higgs
modes, in addition to the known color-flavor-locked condensate. Moreover, the
condensate is applied to explore formations of vortices in the presence of
external magnetic fields. The superfluid-like vortices are constructed for the
magnetic-induced condensate. In the situation including both kinds of
condensates, the theoretical possibility of vortons is suggested and the
formation condition and the energy stability are investigated semi-classically.
