The orthorhombic RPdGe ternary compounds, except YPdGe, are antiferrom
agnetic with negative Curie paramagnetic temperatures. Only the compou
nds with R = Pr, Nd, Th, Dy and Er present ordering temperatures betwe
en 4 K (Nd, Er) and 18 K (Tb). At 1.8 K NdPdGe presents an incommensur
ate magnetic structure of a sine-modulated type with a magnetic wave p
ropagation vector k = [0.0, 0.0, 0.01].
