Abstract

We report the first ESR observation of Nd³⁺ in a metal: cubic LaRh₂. The resonance arises from a Γ₆ ground state and exhibits hyperfine splitting at low temperature, allowing for positive identification. Above about 12 K, the ESR linewidth increases exponentially with temperature. We attribute this increase to the resonance phonon relaxation process involving the first excited state at 125±10 K.
