| 520 | 3 | |a Two of the most powerful tools used to study magnetic materials are inelastic neutron scattering and THz spectroscopy. Because the measured spectra provide a dynamical fingerprint of a magnetic material, those tools enable scientists to unravel the structure of complex magnetic states and to determine the microscopic interactions that produce them. This book discusses the experimental techniques of inelastic neutron scattering and THz spectroscopy and provides the theoretical tools required to analyze their measurements using spin-wave theory. For most materials, this analysis can resolve the microscopic magnetic interactions such as exchange, anisotropy, and Dzyalloshinskii-Moriya interactions. Assuming a background in elementary statistical mechanics and a familiarity with the quantized harmonic oscillator, this book presents a comprehensive review of spin-wave theory and its applications to both inelastic neutron scattering and THz spectroscopy. Spin-wave theory is used to study several model magnetic systems, including non-collinear magnets such as spirals and cycloids that are produced by geometric frustration, competing exchange interactions, or Dzyalloshinskii-Moirya interactions. Several case studies utilizing spin-wave theory to analyze inelastic neutron-scattering and THz spectroscopy measurements are presented. These include both single crystals and powders and both oxides and molecule-based magnets. In addition to sketching the numerical techniques used to fit dynamical spectra based on microscopic models, this book also contains over 70 exercises that can be performed by beginning graduate students. | |

| 545 | |a Randy Fishman was born New York City and received his PhD from Princeton University in 1985. After serving as a faculty member at North Dakota State University, he joined Oak Ridge National Laboratory in 1995 and is currently a Distinguished Research Scientist. He models the complex magnetic states of oxides and molecule-based magnets, often with neutron scatterers and spectroscopists. He is the author of over 160 scientific publications and a Fellow of the American Physical Society. Jaime Fernandez-Baca was born in Lima, Peru. He received training in neutron scattering at the National Bureau of Standards (now the National Institute of Standards and Technology) and at the University of Maryland-College Park, where he received his PhD in 1986 under Jeff Lynn. Afterwards, he joined ORNL as a postdoctoral fellow and is currently a Distinguished Research Scientist at ORNL. Fernandez-Baca's expertise is in the study of the magnetic ordering and spin dynamics of complex oxides and related alloys utilizing neutron scattering techniques. He is the author of over 150 technical articles. Fernandez-Baca is a Fellow of the American Physical Society and the Neutron Scattering Society of America. Toomas Rõõm was born in Tallinn, Estonia and received his PhD from Tartu University in 1993. After working with Tom Timusk at McMaster University, he established a terahertz spectroscopy research group at the National Institute of Chemical Physics and Biophysics in Tallinn, where he has been research professor since 1998. His research interest is combining infrared and terahertz spectroscopy with high magnetic fields and low temperatures to study magnetic and correlated-electron materials. | ||
