Thermo-mechanical sensitivity calibration of nanotorsional magnetometers
arXiv:1203.0998 · doi:10.1063/1.3676231
Abstract
We report on the fabrication of sensitive nanotorsional resonators, which can be utilized as magnetometers for investigating the magnetization dynamics in small magnetic elements. The thermo-mechanical noise is calibrated with the resonator displacement in order to determine the ultimate mechanical torque sensitivity of the magnetometer.
