Vortex lattice pinning is investigated in single-phase sintered bulk PbMo/sub 6/S/sub 8/ and SnMo/sub 6/S/sub 8/ samples with various (between 0.3 and 2.0 ..mu..m) average grain sizes. The sample compositions correspond to certain terminal points of the homogeneity region of the compounds. It is shown that the absolute values and forms of the dependences of the pinning force on the relative induction and on the temperature, P/sub V/(b,T), are significantly influenced by the grain size. The behavior of P/sub V/(b,T) is analyzed in conjunction with the measured vortex-lattice reversible response. It is shown that the principal pinning centers in the investigated samples are the grain boundaries. It follows from an analysis of the results that to increase appreciably the pinning force (the critical current density), especially in strong magnetic fields, it is necessary to strengthen the vortex pinning to the boundaries of the individual crystallites.
