Textbook in PDF format Introductory Solid State Physics: An Emphasis on Magnetism acts as a supplement to students tackling solid state physics at both the undergraduate and graduate level. The BCS theory of superconductivity is not included in undergraduate-level books, because the theory is derived at the graduate level. However, this book uses the equations derived by BCS to calculate the thermodynamic properties of superconductors such as the temperature dependence of the heat capacity using techniques accessible to undergraduates. Also covering topics such as wave diffraction, the essentials of thermodynamics, statistical mechanics and local-moment magnetism, it is useful for those studying solid state physics at any level. Key Features: Includes the BCS theory of superconductivity. Provides material that is accessible to students at all levels. Approaches the subject with a particular emphasis on magnetism
