Study of Y-type Hexaferrite by Means of $\text{}^{57}Fe$ NMR and Electronic Structure Calculations
The electron structure and site preferences of Zn and Fe cations in Y hexaferrite system were calculated. The hyperfine magnetic fields on $\text{}^{57}Fe$ nuclei were determined using WIEN2k and corrections for hyperfine contact interaction. The calculated fields were compared to $\text{}^{57}Fe$ nuclear magnetic resonance (NMR) experiment in $Ba_2Zn_2Fe_{12}O_{22}$ single crystal with an aim of interpretation of experimental NMR spectrum.
