Study of low-energy magnetic excitations in single-crystalline CeIn3 by inelastic neutron scattering

Abstract

Inelastic neutron scattering experiments were performed on single crystals of the heavy-fermion compound CeIn${}_3$ for temperatures below and above the Néel temperature, $T_N$. In the antiferromagnetically ordered phase, well-defined spin-wave excitations with a bandwidth of 2 meV are observed. The spin waves coexist with quasielastic (QE) Kondo-type spin-fluctuations and broadened crystal-field (CF) excitations below $T_N$. Above $T_N$, only the QE and CF excitations persist, with a weak temperature dependence.
