Maciej Kachniarz , Jacek Salach
AbstractThe magnetoelastic Villari effect might be utilized in construction of new type of stress and force sensor. However the magnetic material utilized in such sensor should exhibit adequate magnetoelastic sensitivity and in the current state of knowledge there is a lack of publications considering this issue in relation to ferrites. Thus the presented paper is dedicated to the investigation of magnetoelastic properties of soft magnetic Ni–Zn ferrite, which might be a good material for the core of magnetoelastic sensor, considering its relatively high magnetostriction coefficient. As a result of measurements, magnetoelastic characteristics of the investigated material were obtained for both tensile and compressive stress, including magnetization characteristics under different values of applied mechanical stress. On the basis of obtained results the magnetoelastic sensitivity of the investigated material was specified for different values of magnetizing field amplitude covering the entire magnetization curve range of the material.
