On direct and reverse magnetically operated acoustic effect in nanocomposites

Physics of Magnetic Phenomena

A model description of the direct and reverse acoustomagnetic effect (AME) in nanocrystaline composites produced by solidification of magnetic fluid (MF) is performed, in particular, the frequency, orientation and field dependences of the speed-induced generator voltage in the conducting circuit in the acoustic field and the elastic wave amplitudes generated in the waves in a variable magnetic field in the accompanying constant magnetic fields are addressed. Their values can be derived by setting the distribution function of the easy axes of MF particles, which in turn is controlled by the MF solidification temperature and the “freezing” magnetic field. This provides for nanocomposites with predetermined parameters of the direct and reverse AME.
