  Ferromagnetic ordering with a small magnetic moment is found below 14 K from
SQUID measurements for the compound Ce4Sb1.5Ge1.5. The transport
characteristics of a number of Ce4Sb3-xTx (T = Ge, Si, Sn, Pb, Al) systems were
measured at room temperature, Ce4Sb1.5Ge1.5 demonstrating the highest Seebeck
coefficient. Its transport properties (resistivity, thermal conductivity,
thermoelectric power) are experimentally investigated in detail up to low
temperatures. The Kondo-lattice behavior of resistivity and its anomaly at the
ordering point are found. A comparison with the Wiedemann-Franz law is
performed.
