摘要

我们通过实验研究了表面波和后向体积磁静电波在 YIG/Pt 结构中的自旋泵。研究表明，在自旋波频率与态密度中的范霍夫奇点相对应时，自旋电流的产生效率会增加。这项工作的成果对于开发磁子自旋电子器件具有重要意义。

Spin Pumping in YIG/Pt Structures: Role of van Hove Singularities

The spin pumping in YIG/Pt structures by surface and backward volume magnetostatic waves has been studied experimentally. It has been shown that the efficiency of the generation of the spin current increases at frequencies of spin waves corresponding to van Hove singularities in the density of states. The results of this work are important for the development of magnon spintronics devices.
