本文首次提出了一种用垂直纳米磁逻辑（pNML）实现的1位全加器。介绍了具有垂直磁各向异性的NML理论，说明了普遍多数决定的巨大好处。利用该全加器对复杂逻辑电路的工作原理进行了实验验证。部分聚焦离子束照射用于局部控制各向异性并定制纳米磁体的磁行为。在17 μ m（2）的面积上实现了由3个多数门和4个反相器组成的全加器结构。具有恒定幅度的全局交变场脉冲被用作功率时钟。MFM测试结果验证了结构的功能性和理论的正确性，证明了非易失性场耦合逻辑的工作原理，证明了复杂逻辑电路在垂直纳米磁逻辑中的可行性。
In this paper a 1-bit full adder realized in perpendicular nanomagnetic logic (pNML) is presented for the first time. The theory of NML with perpendicular magnetic anisotropy is introduced illustrating the great benefit of the universal majority decision. The working principle of complex logic circuits is experimentally demonstrated utilizing the presented full adder. Partial focused ion beam irradiation is used to control the anisotropy locally and tailor the magnetic behavior of the nanomagnets. A full adder structure consisting of 3 majority gates and 4 inverters is realized on an area of 17 um(2). Global, alternating field pulses with constant amplitude are used as power clock. MFM measurements demonstrate the functionality of the structure and the validity of the introduced theory.The presented work proves the working principle of non-volatile, field-coupled logic and demonstrates the feasibility of complex logic circuits in perpendicular nanomagnetic logic.
