Abstract:
It has been found that the phase shift phivmin in the synchronous detection block that ensures the minimum amplitude of the EPR lines of ruby, diphenylpicrylhydrazyl, and MnSO4·5H2O, depends on the amplitude of the modulationHm of a stationary magnetic field. The dependence of phivmin on Hm is explained by the inertial nature of the recovery of the stationary states of paramagnetic centers on a change in the magnetic field strength.
Keywords:EPR  spectrum  modulation of the magnetic field strength  phase shift in synchronous-detection block  relaxation of paramagnetic centers
