摘要:
A device includes a first free layer, the first free layer being capable of magnetic polarization using a first electrical current, a fixed layer, the fixed layer having a static magnetic polarization, and a first spacer layer disposed between the first free layer and the fixed layer. The device may also include a second free layer, the second free layer being capable of magnetic polarization using a second electrical current, and a second spacer layer disposed between the second free layer and the fixed layer, wherein the device is operable, via the first electrical current, to store a binary value, the binary value being represented by a resistance characteristic of the first spacer layer, and wherein the device is operable, via the second electrical current, to store a compliment of the binary value, the compliment being represented by a resistance characteristic of the second spacer layer.
摘要:
This disclosure describes an apparatus for detecting impending saturation in magnetic cores. A saturable core, which may be toroidally formed, has an aperture in the circumference of the toroid. Windings are separately wound around the toroid between the aperture and the outer edge of the toroid and between the aperture and the inner edge of the toroid. The windings are serially connected in voltage-opposing relation. When saturation of the core starts to occur in one direction or the other, a voltage unbalance in the windings occurs. This unbalance causes a signal to occur which is detectable and indicates the start of saturation.
