  Chiral perturbation theory predicts the chiral anomaly to induce a so-called
Chiral Soliton Lattice at sufficiently large magnetic fields and baryon
chemical potentials. This state breaks translational invariance in the
direction of the magnetic field and was shown to be unstable with respect to
charged pion condensation. Improving on previous work by considering a
realistic pion mass, we employ methods from type-II superconductivity and
construct a three-dimensional pion (and baryon) crystal perturbatively, close
to the instability curve of the Chiral Soliton Lattice. We find an analogue of
the usual type-I/type-II transition in superconductivity: Along the instability
curve for magnetic fields $eB > 0.12\, {\rm GeV}^2$ and chemical potentials
$\mu< 910\, {\rm MeV}$, this crystal can continuously supersede the Chiral
Soliton Lattice. For smaller magnetic fields the instability curve must be
preceded by a discontinuous transition.
