Laminated film structures composed of exchange-biased and nonmagnetic layers are proposed. Their anisotropy fields can be easily controlled by changing the thickness of the soft magnetic layer. In an anti-parallel-bias laminated film, a stable single-domain-like structure can be formed. The permeability exhibits a maximum value when the demagnetizing field in a patterned film is equal to the exchange-biasing one in a parallel-bias laminated film.
