Abstract
The pair distribution function, non-averaged over magnetic moment orientations of a ferroparticle pair, has been calculated analytically. The influence of three-particle correlations on the most probable configuration of magnetic moments of a ferroparticle pair has been analyzed. In this case the ``head-to-tail" orientation of magnetic moments is the energetically favourable position. The probability of ``head-to-tail" magnetic moment orientation of a ferroparticle pair has been investigated depending on the system parameters and distance between the ferroparticles.
