In magnetoectric laminates, tip masses are used to tune the resonant frequency to low frequencies. It is found in literatures, the tip masses are used in the form of permanent magnet. Does this permanent magnet affect the piezomagnetic response of magnetostrictive layers and the the spin structure as well?

I assume this is a mass that is added to tune the mechanical resonant frequency.
The use of a permanent magnet may be to add a magnet DC bias (two birds with one stone)?
