Abstract
Neutron diffraction measurements on the cubic ferromagnetic Laves phases Tb Ir2 and Ho Ir2 confirm the low molecular moments deduced from magnetic measurements. Partial quenching of the orbital angular momentum of the rare-earth atoms is indicated. The coherent scattering amplitude of Ir was determined to be (1,00 ± 0,02) × 10^-12 cm.
Résumé
Des mesures par diffraction neutronique des phases ferromagnétiques et cubiques de Laves Tb Ir2 et Ho Ir2 confirment les faibles moments moléculaires déduits de mesures magnétiques. Un blocage partiel du moment orbital angulaire des atomes de terre rare est probable. L'amplitude de diffusion cohérente de Ir a été déterminée. Elle est de (1,00 ± 0,02) × 10^-12 cm.
