概要
- 論文の詳細を見る
Subthreshold steady-state absorption under parallel pumping in a quasi-two-dimensional ferromagnet K_2CuF_4 has been observed at a pumping frequency of 8.9 GHz in the temperature range from 1.4 to 4.2 K. The magnon density of states by which the magnitude of the absorption is mainly determined is experimentally revealed near the band edge including the singular point due to weak interlayer exchange interaction. A prospect for parallel pumping in a quasi-one-dimensional ferromagnet is given.
