我们从实验上研究了自旋波移相器中相位积累的线性和非线性控制，它是构成自旋波逻辑器件的关键元件。线性控制是通过产生偏置磁场的局部不均匀来实现的，而非线性控制是基于自旋波色散谱随着自旋波幅度的增加而移动的。我们证明，在同一器件中，这两种机制可以具有相当的效率和相对较小的串扰，这使得它们可以同时用于实现双变量逻辑运算。
We have studied experimentally the linear and nonlinear control over the phase accumulation in a spin-wave phase shifter, which is a key element for construction of spin-wave logic devices. The linear control is realized by creation of a local inhomogeneity of the bias magnetic field, whereas the nonlinear control is based on the shift in the spin-wave dispersion spectrum with the increase in the spin-wave amplitude. We show that in a single device these two mechanisms can have comparable efficiencies and relatively small cross talk, which allows their simultaneous use for realization of dual-argument logic operations.
