Dynamic susceptibility of solid ferrocolloids with chain aggregates

The influence of chain heteroaggregates on the initial dynamic susceptibili ty of solid ferrocolloids was studied. It was found that, if the signal fre quency is sufficiently high, the presence of chains decreases susceptibilit y and increases the frequency corresponding to the maximum of its imaginary part. At low signal frequencies, the chains increases the susceptibility a nd reduces the frequency of the maximum of its imaginary part.
