Application：
Electron spin resonance (ESR), also known as electron paramagnetic resonance (EPR)，has been one of the ideal analysis methods since its high sensitive, nondestructive and nonintrusive features. It has been used in a wide range of areas such as physics, chemistry, materials, biology and medicine, etc..
Electron spin resonance is a microwave resonant phenomenon of the unpaired electrons which are isolated or weak coupled in the matter. In classical mechanics, ESR is described as processing of electron spin moment under a fixed magnetic field, namely Larmor processing. Quantum mechanics describes it as a transition between Zeeman-splitting energy levels which is generated by a magnetic field.
