| Abstract(in English) | We simulated reservoir computing with nanomagnets array composed of 2×10 nanomagnets using macrospin simulation. We used 0 or 1 for input data and a magnetization direction of a nanomagnet was set according to input data. Information was transmitted by controlling uniaxial anisotropy. Stable magnetization directions were calculated by solving the Landau-Lifshitz-Gilbert equation, and they were used as states of reservoir computing. XOR, which requires nonlinear computation, was used for the teacher function. As a result, by calculating magnetization directions with 3 significant figures, it could perform XOR operation with an input delay of three. |
