PURPOSE:To produce a large-sized single crystal of Y3-xBixFe5O12 having high quality, in a short time, by the flux pulling-up method using a BaO-Bi2O3-B2O3 flux. CONSTITUTION:A Y3-xBixFe5O12 single crystal is produced by flux pulling-up method comprising the growth and pulling-up of a single crystal from flux using a seed crystal while decreasing the temperature. In the above process, BaO-Bi2O3-B2O3 is used as the flux. A single crystal having desired plane direction can be produced by the above process by properly selecting the plane direction of the seed crystal, and the diameter of the single crystal can be controlled arbitrarily by controlling the rate of pulling and the rate of temperature decrease. Accordingly a large-sized single crystal of Y3-xBixFe5O12 having high quality can be produced in a short time. |
