Abstract
We developed an atomic force microscopy with the tip position was accu rately controlled through the magnetic interaction between a coil and the magnet fixed behind the cantilever. By incorporating a feedback sy stem, we could control the motion of a soft cantilever (0.68 N/m) in a ir and liquid, and obtain force curves without instabilities originati ng from the strong attractive and adhesive forces between the tip and the sample.
