Abstract

A single crystal of a new ternary silicide Gd_1.2Fe ₄Si_9.8 has been synthesized by the Czochralski method and characterized by X-ray diffraction, magnetization, specific heat and electrical resistivity measurements. It has an isostructure of hexagonal Er _1.2Fe₄Si_9.8 with the lattice parameters of a = 3.93 Å and c = 15.25 Å. Magnetic susceptibility follows the Curie-Weiss law down to 10 K. Antiferromagnetic exchange interaction is estimated from the magnetization measurements. Two broad peaks were found in the specific heat at 3.7 and 23 K.
