Tetragonal equilibrium states of iron
Tetragonal equilibrium states of iron is a scholarly work, published in 1999 in ''Physical Review B''. The main subjects of the publication include tetragonal crystal system, ferromagnetism, density functional theory, antiferromagnetism, lattice, lattice constant, materials science, phase, skyrmion, and condensed matter physics. First-principles total-energy calculations on tetragonal Fe show that the ferromagnetic and antiferromagnetic phases have tetragonal equilibrium states with $c/a>1,$ the fcc value.
