摘要:
We developed an atomic force microscopy with the tip position was accurately controlled through the magnetic interaction between a coil and the magnet fixed behind the cantilever. By incorporating a feedback system, we could control the motion of a soft cantilever (0.68 N/m) in air and liquid, and obtain force curves without instabilities originating from the strong attractive and adhesive forces between the tip and the sample.
