Abstract
The first EPR detection of the non-Kramers ions Cr2+ and Fe2+ in Al2O3 is reported. A technique employing thermal detection is used and shown to be advantageous for strongly coupled ions. It is proposed that the ionic displacements caused by radiofrequency electric fields induce transitions, giving APR-like absorption lineshapes. The mechanism applies to all magnetic ions in noncentrosymmetric sites.Keywords
