论文摘要
我们在德累斯顿高磁场实验室（HLD）上报告了用液体rubidium进行的Alfvén-Wave实验。脉冲磁场达到63吨，超过了54 t的临界值，在该临界值中，AlfVén速度变得等于声速（等离子体 - $β$ unity）。在这个阈值下，我们观察到一个施加的8 kHz CW激发的时期，这是磁波和alfvén波之间参数共振的清晰足迹。
We report Alfvén-wave experiments with liquid rubidium at the Dresden High Magnetic Field Laboratory (HLD). Reaching up to 63 T, the pulsed magnetic field exceeds the critical value of 54 T at which the Alfvén speed becomes equal to the sound speed (plasma-$β$ unity). At this threshold we observe a period doubling of an applied 8 kHz CW excitation, a clear footprint for a parametric resonance between magnetosonic waves and Alfvén waves.
