Heat resistant container for single domain treatment of oxide single crystal and single domain treatment method of oxide single crystal

摘要

Problem to be solved: to suppress the defects such as cracking due to contact of the oxide single crystal to the heat-resistant container in the case where the oxide single crystal is placed in the heat resistant container or the extraction of the oxide single crystal from the heat resistant container, and the workability is improved.Heat resistant containerFor an oxide single crystal embedded in an oxide single crystal powderA heat-resistant container for use in a single domain treatment in which single crystals of single crystals are applied by applying a voltage at a predetermined temperatureThe receiving tray with bottom and wallCylindrical.A cylindrical section placed above the tray sectionEquipped withCylindrical sectionAn oxide single crystal and an oxide single crystal powder can be contained inside.The saucerOxide single crystal powderA cylindrical portion holding oxide single crystal and oxide single crystal powder andAndThe outer diameter of the cylinder isSmaller than the inner diameter of the tray.Diagram
