Y-Ba-Cu-O系列高Tc氧化物超导材科的出现,使超导研究成为当前最热门的课题.随着Tc超过液氮温度,不但使该类超导材料的应用成为可能,而且使缺少低温液氦设备的单位也可以加入到超导研究的行列中.本文介绍一套十分简易的装置,可以用来快速测量超导材料的R-T 曲线,并有较满意的精?
The emergence of Y-Ba-Cu-O series of high Tc oxide superconductors has made superconductivity the hottest topic in the world nowadays.With Tc exceeding the liquid nitrogen temperature, not only the application of such superconducting materials becomes possible, But also makes the lack of cryogenic liquid helium equipment units can also join the ranks of superconducting research.This article describes a very simple device that can be used to quickly measure the superconducting material RT curve and more satisfied with the fine?
