Abstract: An apparatus and associated method may provide a magnetic element can have a thin film deposited on a cryogenic substrate. The thin film can additionally be stress tuned ,during primary annealing to reduce unwanted stress anisotropy. The thin film can be configured to have near zero internal stress after the primary annealing.
