Abstract

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.
