The brief introduction fo Piezomagnetic materials

　　Piezomagnetic material’s characteristics will happen mechanical deformation in the external magnetic field, it is also known as the magnetostrictive material, and its function is used for the conversion of magnetic acoustic or magnetic energy.

　　It is commonly used in the vibration of the ultrasonic generator head , communication equipment , mechanical filters and electrical pulse signal delay line , combined with microwave technology can produce the silenced ( or spin sound ) , devices . It is commonly used in the vibration of the ultrasonic generator head , communication equipment , mechanical filters and electrical pulse signal delay line , combined with microwave technology, it can produce the silenced ( or spin sound ) , devices .

　　Because the alloy material has high mechanical strength, vibration and not burst, the vibration head mostly uses Ni system and the of NiCo Department alloy ; Used in small signals, it mostly use Ni and Alnico Magnets.
