  We investigated the physical properties of low concentration ferroelectric
nematic colloids, using calorimetry, optical methods, infra-red spectroscopy
and capacitance studies. The resulting colloids normally remain homogeneous,
but the nematic orientational coupling is significantly amplified. In
particular cases, the nematic orientation coupling increases by 10% for
particle concentrations of 0.2%. A manifestation of the increased orientational
order is that the clearing temperature of a nematic colloid increases up to 40
Celsius degrees compared to the pure LC host. A theoretical model is proposed
in which the ferroelectric particles induce local dipoles whose effective
interaction is proportional to the square of the orientational order parameter.
