Magnetization, specific heat, and electrical resistivity measurements on single crystals of the noncentrosymmetric actinide based compounds U2Fe12P7 and Th2Fe12P7 are reported. The measurements reveal that U2Fe12P7 displays antiferromagnetic order at a Néel temperature T(N) ≈ 14 K, while Th2Fe12P7 is a metal which exhibits Pauli paramagnetism with no evidence for superconductivity for T ≥ 1.1 K. Magnetization measurements on U2Fe12P7 show complicated magnetic behavior involving the U and, possibly, Fe ions, as well; e.g., hysteretic temperature and field dependences and metamagnetism. Electrical resistivity measurements on U2Fe12P7 also indicate large spin disorder scattering of conduction electrons for T ≥ T(N).
