Kotru, S. Kachroo, B. Wanklyn] Results of optical and scanning electron microscopic and EDAX studies, carried out on structures exhibited by HoFeO3 crystals grown from the PbO-PbF2-B2O3 flux system, are reported. Aluminium and silicon are present as impurities in the crystals studied. EDAX of certain structures indicate formation of magnetoplumbite (PbO · 6Fe2O3) during the flux growth of HoFeO3. Crystallization of HoOF on the HoFeO3 crystal surfaces is also indicated; the process taking place almost at the end of HoFeO3 crystal growth. A variety of microdisc patterns on HoFeO3 crystal surfaces are illustrated. Their formation is attributed to the covering process of impurity phases by the rapidly advancing growth fronts on the HoFeO3 crystal surfaces. Experimental evidence in support of this is offered by exposing the impurity phase buried under the microdisc. Precipitation of the secondary phases during the flux growth of HoFeO3 crystals and their influence on the latter is discussed. Chapman and Hall Ltd, 1986 Kotru P.
