Description

I will describe the development and characterization of a spinning rotor based on a Meissner-levitated ferromagnetic microsphere and a synchronous driving technique. We have achieved rotational frequencies above 2 MHz, close to the disintegration limit. We have measured a damping rate well below 1E-6 Hz in vacuum, corresponding to rotational quality factor above 1E13. Finally, we have demonstrated rotor syncronization to a local oscillator. I will discuss potential applications to sensing and to precision measurements relevant to fundamental physics.
