摘 要: 利用电子顺磁共振能够测得未成对电子的顺磁性物质的g因子,由g因子可以了解顺磁分子内部结构的局部磁场特性,也可以判断其自旋角动量和轨道角动量对电子磁矩的贡献大小。因此测量g因子是了解顺磁性物质特性的一个重要方面。本文从理论上推导出了Landé g因子公式,并研究了不同情况下g因子偏离ge大小的原因,又在此基础上,给出了两种测量g因子的方法。
关 键 词: 凝聚态物理;电子顺磁共振;g因子;标定方法;角动量

Abstract: g-factor is able to be measured by EPR. It is to know the local magnetic field trait of internal configuration of molecule, and also to judge how much the spin angle momentum and the orbit angle momentum contribute to the electron magnetic moment. Therefore, the measurement of g-factor is one of important aspects of knowing paramagnetic matter trait. So, it is to get Land�g-factor from the theory, and to study the reasons why g-factor value deviates from ge in the different situation. In this foundation, a couple of methods to measure g-factor are given.
Key words: condensed matter physics; electron paramagnetic resonance; g-factor; demarcation method; angular momenta
