Static and Dynamic Magnetic Response of the Mixed-Valence State: Cerium-Based Alloys

Static and Dynamic Magnetic Response of the Mixed-Valence State: Cerium-Based Alloys

For the first time crystal-field excitations are observed in the inelastic-neutron-scattering spectra of a mixed-valence system, namely, Ce0.9--xLaxTh0.1. Scaling relationships are established which connect various energy-related quantities, such as the T = 0 Fermi-liquid susceptibility, the valence...

Zusammenfassung:For the first time crystal-field excitations are observed in the inelastic-neutron-scattering spectra of a mixed-valence system, namely, Ce0.9--xLaxTh0.1. Scaling relationships are established which connect various energy-related quantities, such as the T = 0 Fermi-liquid susceptibility, the valence transition temp. and the spin-fluctuation energy as measured by the neutron scattering linewidths.9 refs.--AA
