Spinhyphen;Exchange Interactions of MnCl2in LiCl/KCl Eutectic at High Temperatures

摘要

Spinhyphen;exchange interactions of MnCl2in molten LiCl/KCl eutectic over the temperature range 700deg;mdash;1200deg;K have been studied by the method of electron magnetic resonance spectroscopy. The resonance linewidths are determined by the exchangehyphen;narrowing process under the experimental conditions used in the present investigation.p,the probability that a paramagnetic ionmdash;paramagnetic ion encounter will result in exchange, is found to be given by the expressionpTap;1mdash;exp(mdash;Ceegr;/T), whereCis a constant, eegr; is the solvent viscosity, andTis the absolute temperature.
