This work reports the magnetic properties of sputtered permalloy (Ni80Fe20) multilayers grown changing the anisotropy direction 90° in successive layers. Magnetic measurements show how the saturating field can be controlled by the thickness ratio between different anisotropy layers and how the coercive field is reduced increasing the number of layers. The linearity of the hysteresis loop is also improved when increasing the number of layers. Magnetic measurements are compared to simulations based on a Stoner-Wolfarth magnetization rotation mechanism.read more

Angle-of-incidence anisotropy in evaporated nickel-iron films
TL;DR: It is concluded that deposition at an angle of incidence produces an anisotropy in structural imperfections, which is interpreted in terms of shape and surface magnetic anisotropies as well as magnetostrictive effects.
