  The spin-frustrated conductor Mn$_3$Pt exhibits a characteristic magnetic
structure called partial disorder in which some spin sites can form magnetic
order through the generation of non-ordered sites that locally relieve the
frustration. Here we report the results of a single-crystal inelastic neutron
scattering study of this compound. The measured momentum $\vec{Q}$ correlations
of diffusive magnetic scattering reveal that the paramagnetic phase exhibits
short-range spin fluctuations with the same type of partial disorder. Its
relation to conductivity is also discussed.
