Resumen
A multilayer magnetic system with isotropic and simultaneous magnetization reversal comprising one or more alternating bilayers where each bilayer is formed by two magnetostrictive magnetic materials with magnetostriction coefficients of opposite sign and where the thickness of each layer forming a bilayer is greater than its exchange length or domain wall, characterized in that each bilayer is formed by a Ni 1-x Fe x alloy with a composition such that the magnetostriction coefficient is negative (λ < 0), coupled to a Fe 1-y Ga alloy and with a composition such that the magnetostriction coefficient is positive (λ > 0).
