Abstract
A composite film on a substrate having a first magnetostrictive, magnetoresistive, anisotropic ferromagnetic thin-film provided on that substrate with a second ferromagnetic thin-film provided immediately thereon which is also magnetorestrictive, magnetoresistive, anisotropic, with a composition differing from the first ferromagnetic thin-film. Various parameters of said first and second ferromagnetic thin-films are selected to provide such a composite film with little or no magnetostriction. Such composite films can be used in various devices.
