A new rare-earth intermetallic compound, namely DyGd4Si2Ge2 having the monoclinic Gd5Si2Ge2-type crystal structure at room temperature has been synthesized and its magnetic susceptibility, electrical resistivity and thermoelectric power are measured in the temperature range 20-300 K. Magnetic susceptibility results reveal a transition from a room temperature paramagnetic phase to a ferromagnetic phase around 65 K (TC). Electrical resistivity of DyGd4Si2Ge2 is metal-like and has a T2 dependence at temperatures less than TC. Thermopower displays a change of slope followed by a peak feature just below TC. © 2001 Elsevier Science B.V. All rights reserved.
