We report here the synthesis of a new compound, Gd2PdGe3, crystallizing in
a AlB2-derived hexagonal crystal structure and the results of electrical re
sistivity, magnetoresistance, heat-capacity and magnetic susceptibility mea
surements down to 2 K. The results suggest that this alloy orders antiferro
magnetically below 10 K, exhibiting significant negative magnetoresistance
over a wide temperature range above 10 K. (C) 1999 Elsevier Science S.A. Al
