Abstract:

Theoretical analysis of the dynamic susceptibility and the signal-to-noise ratio for a moderately concentrated suspension of uniaxial monodomain spherical ferroparticles in a solid matrix was performed. It was suggested that the axes of a weak particle magnetization are oriented in one direction and the alternating external magnetic field is parallel to these axes. Magnetodipole interaction of ferroparticles was accounted for by the successive perturbation theory. The effect of this interaction on dynamic response functions corresponding to the external field frequency and a multiple frequency was estimated. It was concluded that the Debye pattern of initial susceptibility disappears as a result of interparticle interactions. Temperature dependences of the components of the dynamic susceptibility and the signal-to-noise ratio pass through maxima; temperatures corresponding to these maxima increase with the parameters of magnetodipole particle interactions.
