Abstract
Implementations disclosed herein provide a method comprising rocking an effective annealing magnetic field between a first positive angle and a second negative angle compared to a desired pinning field orientation in an AFM/PL structure, wherein an angular amplitude of rocking the effective annealing magnetic field between a first positive angle and a second negative angle gradually decreases towards the desired orientation of pinning in the AFM/PL structure.
