In the fiscal year 2021-22, we continued developing the magnon chemistry in several directions. The coupling of magnons with phonons, for example, led to the discovery of a new magnonic molecule of the Kittel mode of two distance magnets through a non-magnetic spacer over mm distances. This work was helped by a thorough theoretical analysis of the magnetoelastic boundary conditions. We also identified the importance of damping by magnon-induced eddy currents in proximity gates by direct imaging using diamond NV-center microscopy. We have been preparing the ground for the magnonics in 2D magnetic systems by carrying out analytic calculation in ferromagnetic single and double van der Waals layers as well as studying ultrathin layers of the magnetic insulator YIG. Making use of the analogies of magnetic and electric dipoles we invented the new field of “ferronics” that studies the elementary excitations of the ferroelectric order. The theoretical study laid the basis of a new Kiban S project led by Prof. K. Uchida from NIMS.

在2021-22财年，我们继续朝多个方向发展磁振子化学。例如，磁振子与声子的耦合导致了一种新的磁振子分子的发现，该分子具有两个距离磁体的Kittel模式，通过一个非磁性间隔物超过mm距离。对磁弹性边界条件进行了深入的理论分析，有助于这项工作的开展。我们还确定了阻尼的重要性，通过直接成像，使用金刚石NV中心显微镜在邻近门磁振子诱导的涡流。 通过对铁磁单、双货车德瓦耳斯层的解析计算以及对磁性绝缘体YIG的双磁层的研究，为二维磁系统中的磁振子研究打下了基础。利用磁偶极子和电偶极子的类比，我们发明了研究铁电秩序的元激发的“铁电子学”新领域。该理论研究为K. NIMS的内田
