Abstract
We report the formation of a compound, Gd2CuGe3, in a AlB2-derived crystal structure and its temperature- (T) dependent magnetic susceptibility, heat-capacity, electrical-resistivity (ρ), and magnetoresistance behavior. The results suggest that this compound orders antiferromagnetically below 12 K. The most notable finding is that the T derivative of ρ is negative below about 25 K, resulting in a minimum in the plot of ρ versus T around this temperature, a feature not very common among Gd alloys.
