| 中文摘要 | 用室温电子自旋共振 (ESR)实验研究单晶LiNbO3中Mn2 +的精细结构和超精细结构 .对ESR谱的分析得出 ,零磁场的能级分裂数值 :自旋角动量能级± 12 〉与± 32 〉之间的间隔为Δε1 =- 5 87× 10 - 4cm- 1 ,而± 32 〉与± 52 〉之间的能级间隔为Δε2 =- 2 6 33× 10 - 4cm- 1 ;其各向异性朗德因子g∥ =2 1810 ,g⊥ =2 0 937;精细结构常数D =- 5 36× 10 - 4cm- 1 ;超精细结构常数A∥ =88 36× 10 - 4cm- 1 ,A⊥ =81 2 0× 10 - 4cm- 1 ,即精细结构相互作用要比超精细结构相互作用大得多 .另外 ,特别值得提到的是实验中还发现两组明显的禁戒跃迁 ,- 32 〉 12 〉和- 12 〉 52 〉.; Fine structure and hyperfine structure of Mn 2+ in LiNbO 3 are analyzed with electron spin resonance (ESR) at room temperature. It is concluded that the zero-field splitting of energy levels of electron spin angular moment between ±12〉 and ±32〉 is Δ ε 1=-587×10 -4cm -1,and that between ±32〉 and ±52〉 is Δ ε 2=-2633×10 -4cm -1. The anisotropic Lande factors are g ∥=2.1810,and g ⊥=2.0937. The fine structure constant is D =-536×10 -4cm -1,and hyperfine structure constants are A ∥=88.36cm -1 and A ⊥=81.20×10 -4cm -1. The interaction action of the fine structure is larger than that of the hyperfine structure. In addition,it is worth paying special attention to the fact that two forbidden transitions -32〉12〉 and -12〉52〉 are found.; 国家重点基础研究发展计划 (批准号:G19990 3 3 0 ); 国家自然科学基金(批准号 :699770 0 5 )资助的课题~~ |
