| 摘 要： | 本文讨论应用连续波方法测量电子自旋——晶格弛豫时间T1的实验技术问题。分析液氮翻滚使T1测量结果很不一致的原因,提出用吹冷气冷冻样品方法,可以解决液氮翻滚对测量T1所产生的影响.用改进的方法测量ZnS:Mn、Cu粉末样品的T1,获得重复性较好的实验结果。

| Abstract: | Several technieal problems for the measurement of electron spin-lattice relaxation T1 by the saturation methods are discussed.When the relaxation time T1 is deter-mined at liquid N2 temperature,the liquid N2 in quartz Dewer containing samples usually boils,therefore T1 is difficult to determine.If the cooling of samples is accomplished by cooling N2 gas flow,then T1 is determined.The results of determining spin-lattiee relaxation time T1 of ZnS:Mn,Cu are attained,and the T1becomes shorter with the formation of Mn2+ clusters. |
