【Abstract】 Electron spin resonance(EPR) is a powerful technique to study the electron structure and dynamics of many materials with unpaired electrons(paramagnetic materials). Nowadays, EPR has been widely applied in chemistry, material, radiation detection, biology, and quantum information processing. Compared with the X-Band EPR, the high frequency/field EPR(HF-EPR) has the advantages of resolution, sensitivity, and initialization. This article is a concise introduction to the history, basic theory, instrumentation, and characteristics of the HF-EPR, and the emphasis on the application of HF-EPR in the research on spin qudits. The progress and future prospects of this analysis technique are also outlined. The HF-EPR could be used as a tool to implement the coherent manipulation of spin qudits, further paving the way toward quantum logic gate operation and quantum algorithm.更多还原
