Аннотация:It is shown that the interaction (local) field distribution in disordered systems with dipolar interparticle interaction transforms from the Lorentzian to the Gaussian when the particle volume concentration is increased. To evaluate correctly the local-field dispersion ${\mathit{h}}^{2}$ in systems with randomly oriented dipoles it is sufficient to take into account the nonmonotonic behavior of the particle radial pair distribution function. For aligned dipoles angular correlations of particle positions in the first coordination sphere play a dominant role, strongly decreasing h${\mathrm{\ifmmode\bar\else\textasciimacron\fi{}}}^{2}$. \textcopyright{} 1996 The American Physical Society.
