This book outlines state-of-the-art studies in the spectroscopy for exotic superconductors, those that exhibit high temperature superconducting transitions or that cannot be explained by traditional theories. It describes a range of analytic tools, including Raman and ultrafast spectroscopy,
photoconductivity, microwave resonance, magnetotransport and X-ray diffraction, and emission Mossbauer spectroscopy. The book draws from both fundamental and applied viewpoints and includes extensive references and detailed descriptions of physical properties. It includes important new research on
the vibrations of the oxygen sublattice and on the application of superconductor assemblies to optical devices. Written by solid-state chemists and physicists, the book is accessible to a broad audience of scientists, engineers, and graduate students interested in condensed matter physics.
