Abstract
A 3-dimensional (3-D) magnetic stray field and the surface structure have been observed using an atomic and magnetic force microscope (A/MFM) with an optical-beam-deflection force detector. Measurement is carried out by operating the microscope as a surface structure observer in constant repulsive force AFM mode. The 3-D magnetic stray field measurement is done in force gradient MFM mode with probe position control above the surface. Initial results have demonstrated that the 3-D magnetic stray field and surface structure of magneto-optical disk can be imaged simultaneously.Keywords
