High Resolution Magnet Systems

EPR - Cryogenic Ltd.

EPR samples with S=1/2 electronic spins exhibiting a narrow signal at G=2 and require magnetic fields of only ca. 3.5 T. However, EPR spectra from S>1/2 spins are typically much broader and have spectral features that spread over magnetic field range of several Tesla. Such fields could be easily achieved with superconducting magnets, but, unlike NMR, these magnets cannot operate in a persistent mode in order to satisfy a wide range of resonant fields required by the experiment.
