Status and trends in high performance magnetic imaging using Scanning Probe Microscopy (SPM)

2016-11-30
A novel method for excitation of Atomic Force Microscope(AFM) cantilevers by means of radiation pressure for imaging has been developed for the first time. Piezo excitation is the most common method for cantilever excitation. However, it has quite a few drawbacks like causing spurious resonance peaks and non-ideal Lorentzian curves. The force exerted by the radiation pressure is quite weak but sufficient to excite the cantilever to tens of nanometers for imaging in vacuum, as the Q increases to few thousands. An amplitude modulated fiber coupled 1.31µm laser is used to excite the cantilever at its resonance and detect the position for MFM imaging as shown in Fig.2.
