| 摘 要： | 本文叙述用脉冲饱和法测量自旋-晶格弛豫时间的实验及其结果。在显示方面使用了倍频同步法以产生基线,便于读取T1。测定了红宝石Cr3+离子的弛豫时间,肯定在77°K时各种跃迁的T1大致相等,但浓度增高时T1降低。

| Abstract: | The experimental technique and results from measuring spin-lattice relaxation times by the pulse saturation method at X band are described. Double frequency is used to synchronize the oscilloscope in order to measure T1 more precisely. The spin lattice relaxation times of Cr3+ in ruby have been measured for several different concentrations. It is concluded that T1 of various transitions are nearly the same, but become shorter apparently with increasing Cr3+ concentration. |
