射频电子顺磁共振实验仪
DEVELOPMENT OF RADIO FREQUENCY ELECTRON PARAMAGNETIC RESONANCE EXPERIMENTAL INSTRUMENT
【摘要】 本文研制的射频段电子顺磁共振实验仪相比于微波段电子顺磁共振实验仪频率小,因此所需磁场小,仅用简单的亥姆霍兹线圈就可以满足实验的需求,可以测量g因子和共振线宽,还可以测量地磁场矢量。本实验仪结构简单、安全、经济实用,用示波器可以观察到共振信号,由此,学生对电子顺磁共振现象具有直观、准确的认识。
【Abstract】 Compared with the microwave electron paramagnetic resonance(EPR) experiment instrument, the radio frequency(RF) EPR experiment instrument developed in this paper has the lower frequency, so it needs smaller magnetic field. Only a simple Helmholtz coil can meet the needs of the experiment. It not only can measure g factor and resonance linewidth, but also can measure the geomagnetic field vector. The RF EPR experiment instrument has advantages in simple structure, safe, economical and practical. The resonance signal can be observed by an oscilloscope, so that students have an intuitive and accurate understanding of EPR phenomenon.
