开发了一种用于微波特性研究的新测量系统。由标准准光介电谐振器技术改进后，用回音壁模式激励的蓝宝石圆柱谐振器沿半径有一个狭窄的狭缝，在狭缝内可以放置一块小尺寸的单晶或薄膜样品。该谐振器由两片 YBCO 薄膜夹在中间，密封在一个专门设计的真空容器中，该真空容器浸泡在液体 4He 中。微波信号通过不锈钢薄壁波导耦合到真空容器，然后通过蓝宝石波导耦合到谐振器。在测量过程中可以精确控制谐振器和两个蓝宝石波导之间的耦合。此外，在真空容器中设计了减压液体4He端口，以将测量范围扩展到低至2.6 K。测试采用高质量的BaFeNiAs单晶磷化物超导体。
A new measurement system for microwave property study has been developed. Modified from the standard quasi-optical dielectric resonator technique, the sapphire cylinder resonator excited with whispering gallery modes has a narrow slit along the radius, within which a piece of small-sized single crystal or thin film sample can be positioned. Sandwiched by two pieces of YBCO films, the resonator is sealed in a specially designed vacuum vessel, which is soaked in liquid 4He. A microwave signal is coupled to the vacuum vessel by stainless steel thin wall waveguides and then to the resonator by sapphire waveguides. Coupling between the resonator and the two sapphire waveguides can be controlled accurately during the measurement. Furthermore, a decompressed liquid 4He port has been designed in the vacuum vessel so as to extend the measurement to lower temperatures down to 2.6 K. A high-quality single crystal pnictide superconductor of BaFeNiAs was used for testing.
