A composite film (F'1) on a substrate (11) having a first magnetostrictive, magnetoresistive, anisotropic ferromagnetic thin-film (F'<1-1>) provided on that substrate with a second ferromagnetic thin-film (11") provided immediately thereon which is also magnetorestrictive, magnetoresistive, anisotropic, with a composition differing from the first ferromagnetic thin-film (F'<1-2>). Various parameters of said first and second ferromagnetic thin-films (F'<1-1>, F'<1-2>) are selected to provide such a composite film (F'<1>) with little or no magnetostriction. Such composite films can be used in various devices (figs 4 and 5). |
