Abstract
An electron spin-based device includes ferromagnetic layers with different coercivities, such that one of such layers is responsive to a magnetic field and the other is fixed. A value of an impedance in the spin based device for a spin polarized current varies in accordance with a relationship between a first changeable magnetization state and a second non-changeable magnetization state associated with such ferromagnetic layers.
