Magnetic and magnetostrictive properties of cube textured nickel for magnetostrictive transducer applications

Magnetic and magnetostrictive properties of {100} <100> textured, polycrystalline nickel sheet have been measured in the <100> direction and compared with a randomly oriented nickel sheet. The {100} <100> textured nickel produced a 51 percent increase in the available magnetostrictive strain energy along with a 21 percent decrease in sound velocity. These improved characteristics when combined with an equivalent electromechanical coupling coefficient and a nearly linear response of magnetostrictive strain to the applied magnetic field, make "cube" textured nickel sheet an attractive new material for many transducer applications.
