摘要
利用自制的低温光声光谱检测系统,对高温超导体YBCO在超导转变前后的光声光谱响应进行测定,得到样品随温度变化的光声强度曲线,并初步作出了解释。根据对已知超导样品的实验测量,进一步说明该低温光声光谱技术是高温超导机理研究的新方法。
Self-made low-temperature photoacoustic spectroscopy detection system for high-temperature superconductors YBCO in the superconducting transition before and after the measured response of photoacoustic spectroscopy was obtained with the sample temperature photoacoustic intensity curve. A preliminary interpretation of the corresponding was made. Based on the known experimental superconducting samples, and the low-temperature photoaeoustic spectroscopy study of high temperature superconducting mechanism of new methods was further illustrated.
