N2 - Temperature and applied magnetic field dependent magnetization measurements on 34 single crystalline samples of (R, R′, R″ ...) Ni2 Ge2 compounds (R, R′, R″, etc. being primarily Gd-Lu, Y), were made. These measurements reveal that, despite extremes in local moment anisotropy, the average de Gennes parameter is a remarkably good predictor of the paramagnetic to antiferromagnetic ordering temperature. In addition, the pronounced metamagnetic phase transitions seen in the low temperature phase of TbNi2 Ge2 are found to be remarkably robust to high substitution levels of Gd and 25% substitutions of other heavy rare earths.
