Itinerant Ferromagnetic Superconductors

ITINERANT FERROMAGNETIC SUPERCONDUCTORS This book provides a comprehensive introduction to the theory of microscopic coexistence of itinerant ferromagnetism and superconductivity in the light of recently discovered U- based compounds. The content covers a brief review of the field and the microscopic theory developed using Green’s function technique and equation of motion method in mean field approximation. Conceptual aspects and formal methodology are emphasized and developed, but the discussion is rooted firmly in practical experimental application. The book covers particularly the physics of coexistence of itinerant ferromagnetism and superconductivity. It is pedagogical in philosophy, and is based on the idea of leading the reader to understanding sophisticated formalism through the study of combined Hamiltonian of BCS and Hubbard which demonstrate the basic ideas of coexistence of two physical phenomena that were previously thought to be incompatible. This book will prove invaluable for students and scientists contemplating research in this field.
