The basic approach in the microscopic theory of binary metal systems has been developed. The electron-ion model Hamiltonian with nonlocal manyparticle interactions was obtained using the statistical operator averaging for the electron-nuclear model over the localized electron states. The role of orthogonalization and exchange effects on the formation of electron-ion interactions is investigated...

It has recently been predicted that certain magnetic materials contain mobile magnetic charges or ‘monopoles’. Here we address the question of whether these magnetic charges and their associated currents (‘magnetricity’) can be directly measured in experiment, without recourse to any material-specific theory. By mapping the problem onto Onsager’s theory of weak electrolytes, we show that this i...
