Magnetism and resistivity of some dilute rare earth-zinc compounds

Measurements have been made from 2K to 300K of the magnetic susceptibilities of polycrystalline specimens of six R2Zn17 and of four RZn12 compounds whose resistivities have also been obtained, where R represents a rare earth. Most of the compounds order antiferromagnetically. The resistivities due to electron-magnon scattering go as T1.38 for GdZn12, T1.45 for TbZn12, T5.9 for SmZn12 and T6.5 for ErZn12, as a function of temperature T. The presence of short range order has been detected far above the Neel points of the two gadolinium compounds.
