Abstract
Commercially available magnetostrictive composites employ the differential magnetostriction exhibited by materials of different composition and are therefore sensitive to temperature changes as well as to variations in magnetic field intensity. In order to overcome this problem a new approach has been adopted, using laminas of the same material which yet possess different magnetostrictive characteristics. It is shown how, by suitable choice of material, the laminas can be prepared from highly textured polycrystalline sheets so that one lamina contains a high proportion of 〈111〉 crystal directions along its length while the other contains mostly 〈100〉 crystal directions along its length. Such laminas are found to exhibit different magnetostrictive coefficients and may be bonded together to form an effective magnetostrictive composite which is inherently insensitive to temperature change.
