Abstract
A magnetic film includes one or more magnetically conductive layers. Each magnetically conductive layer is cracked to form a plurality of first through-cracks defining a plurality of magnetically conductive segments. The first through-cracks extend along a first direction and form a first regular pattern along an orthogonal second direction at a first pitch P, such that a Fourier transform of the first regular pattern has a first peak along the second direction at a first spatial frequency corresponding to the first pitch P. The first through-cracks have an average length Lalong the first direction. L/Pis greater than or equal to 5.
