Traditional electronics employs charge currents to control and transmit information and therefore suffer from energy dissipation due to electron scattering. In the past decade, spin waves (magnons) have been discussed as a more efficient alternative. An important aspect of computing based on magnons is the resonant dynamics' reconfigurability. From this end, nanomagnonics with artificial spin ice offers a wealth of possibilities to control the dynamics. This perspective article reviews experimental and theoretical works on the resonant excitations in the GHz frequency range in artificial spin ice, promising for realizing functional magnonic devices. We discuss both the theoretical formulation and experimental methods to characterize the dynamics in the nanomagnetic arrays. The central part of this perspective is devoted to recent developments targeting full control of the dynamics based on the reprogrammability of the spin-ice microstate with the ultimate goal to realize novel functional devices for logics, computation, and storage concepts based on magnons.

传统的电子设备使用充电电流来控制和传输信息，因此由于电子散射而导致能量耗散。在过去的十年中，自旋波（磁振子）已被讨论为一种更有效的替代方法。基于磁振子的计算的一个重要方面是共振动力学的可重构性。为此，带有人造自旋冰的纳米大磁致动器为控制动力学提供了许多可能性。这篇有远见的文章回顾了在人造自旋冰中GHz频率范围内的共振激发的实验和理论工作，有望实现功能性的大型电子设备。我们讨论了表征纳米磁性阵列动力学的理论公式和实验方法。
