Magnetic logic element with toroidal multiple magnetic films and a method of logic treatment using the same
Abstract:
A magnetic logic element with toroidal magnetic multilayers (5,6,8,9). The magnetic logic element comprises a toroidal closed section which is fabricated by etching a unit of magnetic multilayers (5,6,8,9) deposited on a substrate. Optionally, the magnetic logic element may also comprise a metal core (10) in the closed toroidal section. Said magnetic multilayers (5,6,8,9) unit is arranged on the input signal lines A, B, C and an output signal line O, and then is made into a closed toroidal. Subsequently, on the toroidal magnetic multilayered unit (5,6,8,9), the input signal lines A′, B′, C′ and an output signal line O′ are fabricated by etching. This magnetic logic element can reduce the demagnetization field and the shape anisotropy effectively, leading to the decrease of the reversal field of magnetic free layer. Furthermore, this magnetic logic element has stable working performance and long operation life of the device.
Abstract(Chinese):

具有环形磁性多层（5,6,8,9）的磁性逻辑元件。 磁逻辑元件包括通过蚀刻沉积在衬底上的磁性多层（5,6,8,9）单元制造的环形闭合部分。 可选地，磁逻辑元件还可以包括在闭合环形部分中的金属芯（10）。 所述磁性多层（5,6,8,9）单元布置在输入信号线A，B，C和输出信号线O上，然后制成闭合环形。 随后，在环形磁性多层单元（5,6,8,9）上，通过蚀刻制造输入信号线A'，B'，C'和输出信号线O'。 该磁逻辑元件可有效地减少退磁场和形状各向异性，导致无磁层反转场的减小。 此外，该磁逻辑元件具有稳定的工作性能和较长的使用寿命。
