Abstract: We demonstrate the quantitative measurement of the magnetization ofindividual magnetic nanoparticles MNP using a magnetic force microscopeMFM. The quantitative measurement is realized by calibration of the MFMsignal using an MNP reference sample with traceably determined magnetization. Aresolution of the magnetic moment of the order of 10^-18 Am^2 under ambientconditions is demonstrated which is presently limited by the tip-s magneticmoment and the noise level of the instrument. The calibration scheme can beapplied to practically any MFM and tip thus allowing a wide range of futureapplications e.g. in nanomagnetism and biotechnology.
