The most stable state of the Ae and Aen phases of cold matter situated in a superstrong magnetic field is investigated. It is assumed that the magnetic field is frozen in, that the atomic nuclei form a crystal lattice, and that the electrons constitute a degenerate relativistic perfect gas located in a uniform magnetic field. Expressions are obtained which give the baryon number density and the energy density as functions of magnetic-field strength for different mass numbers and for the most stable state of the cold matter. Thresholds for the emergence of free neutrons and for the electron-nucleon phase are estimated numerically for various values of magnetic-field strength much less than 10 to the 25th power G. It is shown that the threshold for formation of the Aen phase is displaced toward higher densities as magnetic-field strength increases and that the matter will experience a transformation from the Ae phase to the enp phase, bypassing the Aen phase, at magnetic-field strengths of at least about 2 by 10 to the 18th power G.
