| Abstract: | A study of lanthanum ferrite, LaFe12O19, by use of the Mössbauer effect has contributed experimental data on the temperature dependence of the internal magnetic field on the sites of the57Fe nuclei, on isomer shift and on quadrupole splitting in the region from 90 to 820K. The Curie temperature was determined at 697K. The Mössbauer spectra of lanthanum and thallium lanthanum ferrite suggest that a special Fe2+ sublattice is not present. |
