Title

Probing the crystal-field potential in CeFe2Al10 using substituted Nd and Pr ions

Abstract

The compounds from the CeT2Al10 family (T: Ru, Os, Fe) exhibit Kondo-insulator properties, with an unusual competition of strongly anisotropic crystal-field and exchange interactions, as well as c-f hybridization. We propose to probe the crystal-field potential in CeFe2Al10 by using Nd and Pr impurities, which possess a stable 4f shell, as a local sensor at the rare-earth site in inelastic neutron scattering experiments.
