Summary
The researchers from Technische Universität Dresden report about a method that detects in-plane magnetic stray field components by utilizing a split-electrode excitation piezo and simultaneous excitation of a cantilever at its fundamental flexural and torsional modes. This allows for the joint acquisition of traditional vertical mode images and a lateral MFM where the tip–cantilever system is only sensitive to stray fields acting perpendicular to the torsional axis of the cantilever.
