摘要/Abstract

摘要： 通过附加反向直流磁场,使通用的ESR谱仪的磁场实现过零扫描,这样就能记录下某些材料的样品在零场附近微波信号的变化.本文介绍两种附加反向直流磁场的实验方法,即外加补偿的亥姆霍兹线圈,或直接借用ESR谱仪本身的快扫描线圈,来实现过零扫描.

关键词: ESR谱仪, 过零磁场扫描, 低场微波信号

Abstract: A reverse magnetic field was added to a conventional ESR spectrometer in order to get a magnetic field scanning through zero, therefore the microwave signal of a sample at about zero field could be recorded. Two kinds of methods to add reverse magnetic field have been recommended, one is adding compensating Helmholtz coils, another is applying direct current to the rapid scan sweep coils of ESR spectrometer.

Key words: ESR spectrometer, Magnetic field scanning through zero, Low field microwave signal
