Abstract
the complex magnetic susceptibility components were determined for magnetic liquids based on magnetite and on mix ferrite of the type MexZn1-xFe2O4, where Me can be either Ni or Mn. A maxim of the imaginary component of the magnetic susceptibility was observed at freqencies of tens MHz, assigned to relaxation processes of Néel type. The anisotropy constant of particles from the liquids studied was evaluated by using both static and dynamic measurements.
