Exchange interaction effects in the ESR spectra of Eu2 + in LaB6
Published Web Locationhttps://doi.org/10.1016/j.physb.2007.04.053
The electron spin resonance (ESR) spectra of Eu2 +(4 f7, S = frac(7, 2)) in LaB6 single crystal show a single Dysonian resonance for the localized Eu2 + magnetic moments. It is shown that the Eu2 + ions are covalent exchange coupled to the (B) 2p-like host conduction electrons. © 2007 Elsevier B.V. All rights reserved.
