Abstract

Two new ternary equiatomic compounds, CeRhIn and CeCuIn, have been synthesized which are found to crystallize in the hexagonal Fe₂P type structure and CaIn₂ type structure, respectively. The unit cell volume of CeRhIn deviates from that expected on the basis of lanthanide contraction. Its magnetic susceptibility, and resistivity (due to magnetic scattering), both show a broad maximum at about 150 K. The susceptibility of CeCuIn follows Curie-Weiss behaviour between 40 to 300 K and shows a slight deviation from it below 40 K. From these measurements it is concluded that cerium ions are in a mixed-valent state in CeRhIn but in a trivalent state in CeCuIn.
