• Magnetism of first-row transition metal complexes

    The determination of a magnetic susceptibilty depends on the measurement of B/H. Experimentally the Gouy method involves measuring the force on the sample by a magnetic field and is dependent on the tendency of a sample to concentrate a magnetic field within itself. At any given point, dx, of the sample, the force is given by:
