The role of nonlinear quantum electrodynamic effects in dense strongly magnetized matter on the formation of free electrons is evaluated. It is shown that due to the broadening of the energy gap between the electronic ground state and the vacuum state in a strong magnetic field, the electron binding energy of a magnetized atom does not attain relativistic values. The results indicate that the frozen-in magnetic field of a rotating pulsar facilitates electron-positron pair production only near the pulsar's surface and that the crystal lattice formed from nuclei in the presence of magnetic fields becomes markedly more stable if the gyrofrequency of the nuclei is greater than their eigenfrequency.
