MAGNETIC BIASING AND MFM IMAGE-RECONSTRUCTION

A novel experimental technique of magnetic biasing for the Magnetic Fo rce Microscopy (MFM) imaging is introduced. This technique enforces li nearity of the imaging system and, in this way, it facilitates the int erpretation of images of magnetization patterns. The technique of nume rical reconstruction of the curl-free vector magnetization from a raw image obtained by the linearized MFM system is presented. An example i s given which demonstrates the significant difference between the reco nstructed magnetization and the raw image. This stresses the usefulnes s of magnetic biasing and image reconstruction for MFM image interpret ation.
