Simultaneous setting of exchange pinning field magnetization in more than one direction for several thin film structures on a single substrate has been achieved by first orienting the structures as needed. A layer of hard magnetic material is then deposited, suitably patterned to control the direction of its flux, and then magnetized through a single exposure to a strong magnetic field. The assemblage is then thermally annealed (in the absence of any applied field) at a temperature higher than the AFM material blocking temperature, following which the thin film structures are magnetically pinned in the intended directions. |
