Unusual Manifestation of the Spectral Diffusion in the EPR Spectra of Non-Kramers Paramagnetic Centers as Studied by Tunable High-Frequency EPR Spectroscopy

摘要

Magnetic properties of non-Kramers paramagnetic centers (PCs) with integer spin are essentially different from those of Kramers PCs with half-integer spin. For non-Kramers PCs the system of electronic levels is often split up to singlet states in a low-symmetry crystal field.
