The authors treat atomic aspects of TM physics which, unlike the case of simple metals, are rather important since d- and especially f-states retain in a large measure atomic features. They also review applications of the Racah’s angular momentum formalism and Hubbard’s many-electron operator representation in the solid state theory, which are seldom discussed in the literature on the metal theory.
· The book considers the electronic structure of TM from the ‘band’ side and contains a brief review of the methods of band structure calculations, including the density functional approach, with special attention to TM peculiarities. The authors discuss some simple model approaches to the band spectrum and related experimental (especially spectral) data, and consider also theoretical and experimental results concerning the Fermi surfaces. A chapter is devoted to thermodynamical properties of TM: cohesive energy and related properties, stability of crystal structures, and specific heat, electronic contributions.
· The chapter on magnetic properties discusses various theoretical models describing highly correlated d- and f-electrons. Appendices related to this chapter demonstrate concrete practical applications of the many-electron models, mainly within the simple method of double-time retarded Green’s functions.
· The chapter on transport phenomena in TM demonstrates a number of peculiarities in comparison with simple metals, e.g., occurrence of spontaneous (anomalous) effects. Quantitative treatment of these effects is performed with the use of density-matrix approach in the operator form.
· The book also discusses some questions of the anomalous f-compound theory, in particular various mechanisms for occurrence of ‘heavy’ electron mass and the problem of competition between the Kondo effect and magnetic interactions.
