摘要
DC SQUID NMR在研究凝聚态体系 ,尤其在研究低温下量子有序态等方面是一项非常有价值的技术。文中描述了在带有宽带电子设备的商业 DC SQUID基础上建立起宽带脉冲谱仪 ,以及马鞍形激发线圈、采集线圈和低温装置的设计 ,并测量了铂样品在 4.2 Kz温度下的 NMR信号。
SQUID Nuclear Magnetic Resonance is a valuable technique in the study of condensed matter systems, particularly for the study of quantum ordered states at low temperatures. This paper describes the founding of a broadband-pulsed NMR spectrometer based on a commercial DC SQUID amplifier with wideband electronics, and the design of saddle-shaped transmitter coil & pickup coil as well as the design of cryogenic apparatus.
