Spin relaxation of Mn ions in rare earth manganites in paramagnetic region

摘要

Role of bottlenecked spin relaxation and proportionality between small polaron hopping conduc- tivity and electron paramagnetic resonance (EPR) linewidth (intensity) was emphasized. This idea gave a background for several experimental and theoretical investigations and it was start- ing point for its further generalization on variable range hopping conductivity and its influence on EPR linewidth in rare earth manganites.
