Exchange amplification and magnetic impurity oscillation (MIO) quenching in antiferromagnets (AF)
Prokhorov A. S. , Rudashevskii E. G.
The anomalously high intensity of the absorption line of Mn2+ in the antiferromagnet CoF2 (impurity/*afmr~1) at a very low Mn2+ concentration (c~ 0.01-0.03%) has been observed experimentally and is explained theoretically. The amplification effect vanishes when the MIO fall between two (AFMR) frequencies.
