Abstract
According to embodiments of the present invention, a magnetoresistive device is provided. The magnetoresistive device includes at least two ferromagnetic soft layers, wherein the at least two ferromagnetic soft layers have different ranges of magnetization switching frequencies. Further embodiments provide a magnetoresistive device including at least two oscillating ferromagnetic structures, wherein ranges of operating current amplitudes at which oscillations are induced for the at least two oscillating ferromagnetic structures are different. According to further embodiments of the present invention, writing methods for the magnetoresistive devices are provided.
