Some compounds which were recently synthesized for the first time, Ce₃Pd₂oGe₆ and Ce₃Pd₂₀Si₆, have a previously unknown type of crystalline superstructure. The temperature dependence of the resistivity and also the temperature dependence and the field dependence of the magnetic moment have been measured over the temperature range 4-300 К in magnetic fields up to 5 kOe. The resistivity increases logarithmically at low temperatures, indicating a possible Kondo effect in this system. © 1995 American Institute of Physics.
