Abstract

Several growing modes including the bottom growth, the growth on a thermocouple ball and the top seeded growth, were tested to grow BaFe~12−2__x__~Mg~x~Ti~x~O~19~ and BaFe~12−x~Ga~x~O~19~ magnetoplumbite single crystals from the Na~2~OBaO flux. Disadvantages of the bottom growth, inhomogeneities, inclusions, difficult separation of the crystals were restricted by using of the top‐seeded growth and by optimization of the ACRT program.

## Abstract Transparent ZnO crystals were obtained by the flux Bridgman method from high temperature solution of 22 mol% ZnO‐78 mol% PbF~2~ system. The influence of annealing temperatures on the photoluminescence (PL) of ZnO crystal was investigated. An ultraviolet emission peak at about 379 nm was
