The authors grew crystals of CaLnA10/sub 4/ by the Czochralski method at oxygen partial pressures of 10-/sup 5/ to 10-/sup 2/ Pa. The effect of oxygen partial pressure is due to the incongruent volatilization of oxides from CaLnA10/sub 4/ melts, with formation of defects dependent on the excess or deficiency of oxygen in the lattice. Cleavage, observed along the (100) plane, is associated with the cellular growth of CaLnA10/sub 4/ with concentrational supercooling.
