Magnetic Actuation and Feedback Cooling of a Cavity Optomechanical Torque Sensor
P. H. Kim, B. D. Hauer, T. J. Clark +3
We demonstrate the integration of a mesoscopic ferromagnetic needle with a cavity optomechanical torsional resonator, and its use for quantitative determination of the needle's mag…
