Abstract
Embodiments are directed to a method of forming a laminated magnetic inductor and resulting structures having anisotropic magnetic layers. A first magnetic stack is formed having one or more magnetic layers alternating with one or more insulating layers. A trench is formed in the first magnetic stack oriented such that an axis of the trench is perpendicular to a hard axis of the magnetic inductor. The trench is filled with a dielectric material.
