摘要
The present invention provides a multi-mode torsional oscillator for use in a force sensing microscopy tool, In one embodiment of the present invention a sample is mounted on a multi-mode torsional oscillator. A magnetic field generator polarizes the sample and couples a moment of the sample to the multi-mode torsional oscillator. A sensing system detects the motion of the multi-mode torsional oscillator in response to forces exerted on the sample and provides an output signal. A processor receives the output signal and processes the output signal to reproduce a data representative of the moments contained within the sample.
