“…The simulations were based on ab initio calculations of electron structure of Ba 2 Zn 2 Fe 12 O 22 using WIEN2k [6]. In contrast to our previous paper [7] the crystal structure was fully relaxed -both lattice parameters (c/a and unit cell volume) and internal structural parameters were optimized. The hyperfine magnetic fields and electric field gradients on Zn nuclei were calculated for γ = 0, 1/2, 1 and linearly interpolated in between.…”

“…All cations (Me +2 and Fe +3 ) are positioned in six specific crystallographic sites: two tetrahedral sites and four octahedral sites. For example, the Zn 2+ cations prefer to occupy tetrahedral sites, together with the Fe 3+ cations in Ba2-xSrxZn2Fe12O22 [14,15]. Using the qualitative approach and magnetic data, [16] predicted the orientation of the magnetic moments in the Y-type ferrite sublattices and the relative strength of the super exchange interactions.…”
