A theoretical analysis of the dynamical magnetic susceptibility of a frozen nondilute ferrocolloid is presented. The steric and dipole-dipole interactions between ferroparticles are taken into account. Two systems are studied. The first is the homogeneous solid ferrocolloid with separate individual particles. The second is a ferrocolloid with heterogeneous chainlike aggregates. The effect of the magnetodipole interparticle interaction on the real and imaginary parts of the dynamical susceptibilities of these systems is estimated.
