A mechanism is proposed for transferring magnon energy from one ferromagnet to another by tunneling magnons through a bridging ferromagnetic wire that connects ferromagnets. In the framework of the model of Bose gas for the magnons, expressions are found for the power of the transferred magnon energy from a ferromagnet having a higher temperature to a colder ferromagnet. It is shown how the efficiency of tunneling transport depends on the parameters of exchange interactions in the “ferromagnet-wire-ferromagnet” system, the single-ion anisotropy of the structural units of the system, and the magnetic field. As an example, the role of single-ion anisotropy in the formation of resonant and non-resonant transmission of magnons between ferromagnets and adjacent wire terminal units is shown, which accordingly significantly enhances or weakens the tunneling flow of magnons from one ferromagnet to another.

穿过终止铁磁链的隧道磁振子流

提出了一种机制，通过将磁振子穿过连接铁磁体的桥接铁磁线，将磁振子能量从一个铁磁体转移到另一个铁磁体。在用于磁振子的玻色气体模型的框架中，找到了从具有较高温度的铁磁体转移到较冷的铁磁体的磁振子能量的功率表达式。显示了隧道传输的效率如何取决于“铁磁-线-铁磁”系统中的交换相互作用参数、系统结构单元的单离子各向异性和磁场。举例说明了单离子各向异性在铁磁体与相邻导线终端单元之间磁振子共振和非共振传输形成中的作用，
