ResumoA detailed study of the transport properties of the solid solutions M1−xM′xF2+x (M=Sr, Pb; M′=Sb, Bi) and M1−xM″xF2+2x (M″=Zr, Th) has been carried out for x<0.10. Contrary to solid solutions of strontium, solid solutions of lead show for a very small value of x (x = 0.10 forPb1−xM′xF2+x, x = 0.005 for Pb1−xM″'xF2+2x) a minimum of conductivity associated with a maximum of activation energy. Hypotheses are proposed to explain the results.
