Multifunctional Piezomagnetic Ferrite Materials and Their Newly Acoustical and Vibration Control Devices

摘要

The design, preparation of newly multipurpose ferrites (i.e., a magnetoelectric ceramic materials) Ba6-xR2x(Nb1-xFe2+x)O3, etc, which it exhibiting the piezoelectricity and the piezomagnetic effect, then, preparation and selection of magnetorheological fluids (MRF) have been studied, respectively. The functional integrated devices which is a newly acoustical and vibration control devices combining multipurpose ferrites Ba6-xR2x(Nb1-xFe2+x)O3, etc and magnetorheological fluids, and their applications have been investigated, and, emphasis was given to the applications in acoustics and vibration control, etc, as may be noted.
