利用电子自旋共振技术在室温下研究了纯蓝宝石或未经掺杂的单晶蓝宝石的顺磁自旋。特别是，将纯蓝宝石的自旋密度与商用蓝宝石的自旋密度进行了比较。在市售蓝宝石中检测到四种信号，它们的自旋密度都在1015cm‐3量级。结果发现，对于纯蓝宝石，其中一个缺失，其余三个密度较低，约为1014cm‐3或更低。（©2013 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim）
Paramagnetic spin is investigated using electron spin resonance technique at room temperature for a pure sapphire, or single crystalline sapphire that is made without any intentional doping. In particular, the spin density of the pure sapphire is compared with that of a commercial available sapphire. Four kinds of signals are detected for commercially available sapphire, all of which have spin density on the order of 1015cm‐3. It is found that for the pure sapphire, one of them is missing and rest of the three have lower density on the order of 1014cm‐3or lower. (© 2013 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
