Abstract

Crystals of BaMnxTiyFe12-(x+y)O19 were grown by spontaneous nucleation in slowly cooled high temperature solutions (HTS method). Bi2O3, BaB2O4, Na2O and NaFeO2 were tested as fluxing salts and the crystallization conditions and the growth results are reported, as a function of different fluxes. Distribution coefficients of elements were deduced from the crystal stoichiometry measured by atomic absorption and microprobe analysis. Crystal structure, lattice parameters, and Curie temperature of crystals were also determined. They were found to be similar to those of polycrystals having the same chemical composition.
