Controlling Parameter

As basis of the big diameter crystal development, the single crystal automatic growth is the most important technique for system standardization and mass production. In this article, author introduced a new useful way for the single crystal automatic growth of float zone. By setting the growth interval and controlling parameter, PLC controller could automatically control the single crystal growth when the single crystal’s diameter is greater than 50mm. This method applied to the machine system can greatly reduce the fault of manual operation as well as labor intensity. Also it improved the single crystal quality which increases the ability to develop big diameter single crystal in the future.

The Impact

We report on the synthesis and physical properties of cm-sized CoGeO3 single crystals grown in a high pressure mirror furnace at pressures of 80 bar. Direction dependent magnetic susceptibility measurements on our single crystals reveal highly anisotropic magnetic properties that we attribute to the impact of strong single ion anisotropy appearing in this system with TN∼33.5 K. Furthermore, we observe effective magnetic moments that are exceeding the spin only values of the Co ions, which reveals the presence of sizable orbital moments in CoGeO3.

Halogen Lamps

We report the single-crystal growth of the unconventional superconductor Sr2RuO4, on which research has reached a turning point recently. In order to optimize the quality of crystals grown by the floating-zone method using an infrared image furnace, we focus on an improvement of the structure of the filament in the halogen lamps. By reducing the thickness of the total filament, the form of the molten zone was narrowed. More importantly, the molten zone was observed to be more stable during the growth process. Finally, we obtained the crystals with a length of 12 cm. Additionally, the grown crystal has high quality, displaying the 1.5 K transition temperature expected only for the purest crystals. We also discuss the availability of the newly developed halogen lamps.
