Abstract

Crack- and bubble-free Cu^<2+>-substituted Ca_<12>Al_<14>O_<33> crystals were grown successfully using the feed over 0.5 at%Cu by infrared-heating FZ method. Cu^<2+>-doping may stabilize the molten zone during growth, and change the solid-liquid interface of the molten zone from concave close to flat.
