Supermagnetism of atomic nuclei, clusters, and their ensembles

A microscopic quantum approach to describing supermagnetism is developed based on the thermodynamic formalism considering shell effects. Quantitative description of properties of magnetised atomic nuclei in terms of the Zeeman magnetic susceptibility, and cluster superparamagnetism as the Paschen-Back effect with shell corrections are proposed. An increase of neutron-nuclear scattering cross section in a magnetic field is shown. Magnetic effects are established to lead to a shift towards smaller mass numbers of abundance peaks of synthesis products of atomic nuclei and clusters. Concepts of critical behaviour of the van der Waals droplets, superferromagnetism and self-organized criticality in magnetodynamics of ensembles of atomic nuclei and clusters are introduced and justified. Model- independent analytical tools are proposed, justified and applied to quantify and study the critical behaviour corresponding to the liquid-gas phase transition, self- organized criticality in atomic nuclei, clusters and their ensembles. Applications to magneto resistors and -emitters are considered.
