论文摘要
我们报告了超导射频（SRF）腔内内部内部毫米大小的永久磁铁的磁悬浮。据我们所知，这是关于在SRF腔内悬浮磁铁的第一项实验性工作。该空腔是由6061铝制成的同轴季度波浪微波谐振器，共振频率为10GHz，负载Q为1400。圆柱磁铁（N50）的高度为1毫米，直径为0.75 mm，质量为4 mg，质量为4 mg，并且在1.44 tep.144 tep.144 tipe a empecs a 140 time a 140 time time。在几个加热和冷却周期中，我们的测量是一致的。我们的工作为新型的光学系统提供了一条途径。
We report on the magnetic levitation of a millimeter sized neodymium permanent magnet within the interior of a superconducting radio frequency (SRF) cavity. To the best of our knowledge, this is the first experimental work on levitating a magnet within an SRF cavity. The cavity is a coaxial quarter wave microwave resonator made from 6061 aluminum, having a resonance frequency of 10GHz and a loaded Q of 1400. The cylindrical magnet (N50) has a height of 1 mm, a diameter of 0.75 mm, a mass of 4 mg, and a remanence of 1.44 T. This produces a peak magnetic field 140 times greater than the critical field of aluminum. Our measurements are consistent over several heating and cooling cycles. Our work provides a path towards a novel optomechanical system.
