Parametric interaction in the Terfenol-D based magnetostrictive composite and nickel ferrite

Abstract

The parametric interaction between electomagnetic pumping field and magnetoelastic oscillations in the Terfenol-D based composite has been studied. An original high-sensitivity expiremental technique to study the pulse pumping influence on the decay of magnetoelastic oscillations in the sub-threshold parametric mode in described. The results obtained for the Terfenol-D based composite are compared with data for the polycrystalline nickel ferrite.
