Abstract
The invention includes a conductor with a first side and a second side. The conductor may be sized to have a cross-section diameter substantially similar to a Fermi wavelength of electrons in the conductor, the cross-section diameter being taken substantially perpendicular to a primary direction in which current could flow through the conductor. The conductor size may be selected so that when a magnetic field less than a threshold value is applied to the conductor, the first side of the conductor has a first magnetic state and the second side of the conductor has a second magnetic state. However, when a magnetic field of sufficient strength is applied to the magnetic conductor the first side and the second side will be caused to have the same magnetic state. The material of the conductor may be selected from those for which magnetoresistance magnitude of the material oscillates as a function of the material's cross-sectional area, and the cross-sectional area of the conductor may be selected to correspond to a peak of the function.
