EPR has applications in studying and monitoring a wide range of materials, starting from defects in semiconductors over free radicals in the blood to metal catalysts in hydrogen fuel production. EPR measurements are typically performed in moderate static magnetic fields around 0.3T, corresponding to EPR frequencies around 9GHz. This combination of field and frequency is commonly used due to the relative ease of generation of 0.3T
