Abstract

The temperature dependences of the resistivity, the magnetic susceptibility, and the thermoelectric power were studied in CeSi 2-xGa x Kondo lattices (0les xles1.3) having the alpha-ThSi 2 structure. Measurements were made at 1.7< T<300 K. It was found that, as the gallium content x increases, a transition from a high to a low Kondo temperature TK occurs at xap0.2-0.3. This is an analog of the alpha-gamma transition in metallic cerium. It was also found that when 0.1les xles1.3 the CeSi 2-xGa x alloys pass from the paramagnetic to the ferromagnetic state at a temperature TMlsim12 K. This temperature is almost independent of x near the phase transition; for 0.7lsim xles1.3, it falls from 12 K at x=0.7 to 5 K at x=1.3, probably indicating a d...
