Exchange interaction of Eu2+ -Sm2+ and Mn2+ -Sm2+ in samarium chalcogenides observed by electron paramagnetic resonance

View publication

Abstract

Electron paramagnetic resonance of Eu2+ in various samarium chalcogenides and Mn2+ in SmTe have been observed. The g values are shifted by as much as 10% from their usual values near g=2. The large g shifts are described in terms of the impurity-samarium exchange interactions. © 1971 The American Physical Society.
