The use of Henkel plots as a tool to analyze the type and strength of interaction between particles in fine magnetic particle systems is wide spread. It is commonly accepted that noninteracting systems in general show linear Henkel plots, while interacting systems show curved plots. Using extensive Monte Carlo simulations Henkel plots for noninteracting and interacting systems of particles that show different anisotropies are studied. It is found that a direct relation between linearity and noninteraction exists only for systems of uniaxial particles at low temperatures, while particles with cubic anisotropy always show positive deviation of the Henkel plot in the whole range of temperatures. On the other hand, dipolar interaction always results in negative deviation. In the case of particles with cubic anisotropy and dipolar interaction, the deviation changes gradually from positive to negative with increasing strength of the interaction. © 2000 American Institute of Physics.
