Diamagnetism of graphite

WebThe abnormal diamagnetism of graphite is thus more or less confined to one direction. Further, this abnormal diamagnetism is very sensitive to any chemical treatment of the crystal. For example ... WebThe electronic energy bands of graphite were studied by the Bloch method, and the diamagnetic susceptibility was calculated. The calculated value of the main term in Peierls' constant susceptibility is about 0.3 times the experimental value, and the theoretical value of periods of two types with regard to the de Haas-van Alphen effect is about 2.5 times the …

WebDiamagnetism is the key to this experiment, and provides the extra stabilizing force needed. We'll be using carbon-graphite and bismuth because they have the strongest … If a powerful magnet (such as a supermagnet) is covered with a layer of water (that is thin compared to the diameter of the magnet) then the field of the magnet significantly repels the water. This causes a slight dimple in the water's surface that may be seen by a reflection in its surface. Diamagnets may be levitated in stable equilibrium in a magnetic field, with no power consumption.
