摘要/Abstract

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。

关键词: 弛豫时间T₁, 样品的冷冻

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.

Key words: Relaxation time T₁, Cooling of samples
