The results of magnatization measurements down to 1.8 K on polycrystalline R 2Ti 3Ge 4 (R= Sc, Gd, Tb, Dy, Ho and Er) compounds of orthorhombic Sm 5Ge 4-type were presented. The Gd 2Ti 3Ge 4 was found to be a ferromagnet below 32 K while other R 2Ti 3Ge 4 compounds, with magnetic rare earths, undergo a low temperature antiferromagnetic transition. It was shown that the effective magnetic moment (μ eff) values obtained from the Curie-Weiss paramagnetic susceptibility correspond to that of R 3+ ions. The electric resistivity of these compounds was dominated by electron-phonon scattering above 20 K.
