Abstract
The z-component of both the magnetization and the stray field of a nanomete r sized single domain magnetic Co/Pt multilayer dot with perpendicular magn etic anisotropy is determined quantitatively within the point probe approxi mation by magnetic force microscopy (MFM). The MFM tip used is calibrated b y probing omega-shaped nanosized current rings fabricated by electron-beam lithography. Since the stray field geometry of the dot and the current ring s are similar, the calibrated tip can be used to determine quantitatively t he magnetization and the stray field of the dot with perpendicular magnetic anisotropy.
