论文摘要
超导体对磁铁的悬浮一直是探索量子机械现象的活跃领域。使用的技术之一是测量放置在超导微波腔内的磁铁的悬浮。可以通过测量微波频率的变化来探测悬浮高度。在这里，我们报告了使用Meissner vevitated的永久磁铁的微波腔共振频率变化的测量值。谐振频率和质量因子的变化是根据输入功率和温度的函数测量的。谐振频率的变化很可能是由于磁铁与微波腔内的射频场的相互作用所致。
Levitation of a magnet by superconductor has been an active area of research to explore the quantum mechanical phenomenon. One of the techniques used is to measure the levitation of a magnet placed inside the superconducting microwave cavity. The levitation height can be probed by measuring the change in microwave frequency. Here, we report measurements of the change in resonance frequency of the microwave cavity with the Meissner-levitated permanent magnet. The change in resonant frequency and quality factor was measured as a function of input power and temperature. The change in resonate frequency is likely due to the interaction of the magnet with the radio-frequency field inside the microwave cavity.
