<p>A process for producing a single crystal of SrLaGaO4 by the Czochralski process using the following oxide as a melt of raw material: SrxLayGazOw wherein z >/= x, y >/= x, 0.28 </= x </= 0.325, x+y+z=1, and w=(2x+3y+3z)/2. Preferably the melt is formed by rotating the raw material, and further preferably the single crystal is produced in an atmosphere containing reduced amounts of steam and carbon dioxide.</p> |
