Abstract
Doping effects on thermal diffusivity have been investigated in pyrochlore Sm_2-xSr_xMo₂O₇(0.2 $\le$ x $\le$ 0.6) by means of mirage effect at 300K. Substitution of the Sr ions for Sm ions increases the value of the thermal diffusivity from 0.49 cm²/s at x=0.2 to 0.58 cm²/s at x=0.6. The increase of the thermal diffusivity is ascribed to the variation of the structure of the pyrochlore
