Hyperfine interactions in magnetoelectric hexaferrite system
Original language description
Nuclear magnetic resonance (NMR) in Y-hexaferrite system (Ba1-xSrx)2Zn2Fe12O22 was measured on both monocrystalline and polycrystalline samples at liquid helium temperature. Corresponding ab-initio calculation of the hyperfine parameters was also performed. The signal from 57Fe was detected in the frequency interval 65-76 MHz, while NMR spectrum of 67Zn nuclei occurs between 15 and 30 MHz. Due to the disorder in two tetrahedral sublattices occupied partly by Zn and partly by Fe, the NMR lines are broadand the spectra are poorly resolved. Comparison between the experimentally observed 67Zn spectra and the spectra modelled using the calculated hyperfine parameters was made. It indicates that the spectra of 67Zn can be used to determine the distributionof Zn and Fe between the two tetrahedral sublattices.
