Spherical spin-orientation degeneracy of basic antiferromagnetic configurations due to the dipolar interaction in cubic lattices
Eugene V. Kholopov
Based on a simple general relation for the Lorentz field, the precise values are obtained for the energies of ferromagnetic and basic antiferromagnetic states in sc, bcc, fcc, and…
Pyroelectric vector and related polarization effects
Eugene V. Kholopov
The principal fact that the pyroelectric vector $\Pb^0$ typical of polar crystals is invisible in equilibrium has been verified. Nevertheless, the general formula for $\Pb^0$ as a…
Local lattice potentials and steady-state vacancies in ionic crystals
Eugene V. Kholopov
Basing on peculiarities of local potentials, the two principal trends in vacancy formation are revealed. The proximity to the threshold of local ionic stability due to a giant pote…
Translational invariance of Coulomb series and symmetric potentials in crystals
Eugene V. Kholopov
It is shown that Coulomb series are to be considered within a special mode of summation so as to describe bulk properties of crystals. The translational invariance is then an expli…
Crystal potentials under invariant periodic boundary conditions at infinity
Eugene V. Kholopov
The definiteness of bulk electrostatic potentials in solids under periodic boundary conditions defined in an invariant manner has been proved in the general case of triclinic symme…
