Growth of Lead and Aluminum Substituted Barium Hexaferrite Single Crystals from Lead Oxide Flux

Article Preview

Abstract:

Lead and aluminum substituted barium hexaferrite (Ba,Pb)Fe_12–хAl_хO₁₉ single crystals were grown from lead oxide flux at 1260 °C as hexagonal plates with sizes of about 2 mm. A maximum substitution level of x = 4.82 was achieved for the first time for bulk single crystals. The variation of the unit cell parameters with Al content is in good agreement with literature data on exclusively Al substituted barium hexaferrite, while the substitution of Ba by Pb has hardly any influence. Similarly, Pb has only a negligible influence on the magnetic properties, while Al substitution significantly reduces the saturation magnetization in a very similar manner as known from Pb-free barium hexaferrite.
