Large single domain 123 material produced by seeding with single crystal rare earth barium copper oxide single crystals |
摘要 |
A method of fabricating bulk YBa2Cu3Ox where compressed powder oxides and/or carbonates of Y and Ba and Cu present in mole ratios to form YBa2Cu3Ox are heated in the presence of an Nd1+xBa2-xCu3Oy seed crystal to a temperature sufficient to form a liquid phase in the YBa2Cu3Ox while maintaining the seed crystal solid. The materials are slowly cooled to provide a YBa2Cu3Ox material having a predetermined number of domains between 1 and 5. Crack-free single domain materials can be formed using either plate shaped seed crystals or cube shaped seed crystals with a pedestal of preferential orientation material. |
