| Abstract: | Anomalous diamagnetism in small magnetic fields may be observed in systems consisting of size-quantized metallic clusters. With the increase of magnetic field the diamagnetic susceptibility decreases until ordinary values χ0 ～ 10-5 -10-6. The conditions for the existence of anomalous paramagnetism and orbital ferromagnetism in such systems are also discussed. An increase of the diamagnetic susceptibility in anisotropic semiconductors due to impurities is predicted. |
