Orthorhombic structure of viewed along the axis (left) and axis (right). Sr is shown as large green spheres, and Sr as small blue spheres. Note the clearly noncubic structure.
Calculated electronic density of states of on a per formula unit basis as obtained with the Engel–Vosko GGA. Projections onto the two inequivalent I LAPW spheres are also shown.
Real and imaginary dielectric tensor components as a function of energy based on the Engel–Vosko electronic structure.
