It is shown that an introduction of an iron impurity into ternary molybdenum chalcogenides such as PbMo6S8, in addition to strongly suppressing the superconductivity observed earlier, produces large minima in the temperature dependence of the electrical resistance. This effect correlates with the effective magnetic moment of the impurity and with the density of the electronic states.
