Abstract:

The magnetization, anisotropy field and Mossbauer spectra of single-crystal compositions in the system BaFe12-x-y-zZnxTiyMnzO19 were investigated between 4.2 and 300K. The magnetization generally decreases both as a function of increasing substituent and temperature. The anisotropy field decreases with increasing substituents but changes little as a function of temperature above 25K for most compositions. The quadrupole splitting at 77K differs little from that found at room temperature while the hyperfine fields have increased considerably. The magnetic moments H infinity, T 0 were computed and together with the Mossbauer data and analytical data a cation distribution was deduced. Author
