Herb A. Mook, Jr.
For neutron scattering studies of condensed matter physics, particularly investigations of transition metal magnetism and quantum fluids, and for the development of novel scattering techniques. Dr. Mook received his B.A. degree from Williams College in 1960 and his M.S. and Ph.D. degrees in physics in 1961 and 1965 from Harvard University. He joined the Solid State Division staff at ORNL in 1965. Throughout his career at ORNL, Dr. Mook has conducted neutron scattering research on a broad spectrum of topics. He is best known for his pioneering research on the magnetic excitations of transition-metal ferromagnets and the observation of itinerant electron effects in these materials. He has had a longstanding interest in quantum fluids and is well known for his experiments establishing the presence of Bose Einstein condensation in 4He. Dr. Mook was the first to establish the coexistence of superconductivity and magnetism in the rare-earth rhodium borides, for which he received the U.S. Department of Energy's 1982 Award for Outstanding Scientific Accomplishments in Solid State Physics. His present research activities are mostly
concerned with neutron studies of high-temperature superconducting materials. He and his
collaborators were the first to observe the vortex lattice in the high-Tc
materials by neutron scattering and the first to directly observe vortex lattice melting.
He has also used neutrons to probe the interaction between superconductivity and magnetism
and to directly observe the opening of a superconducting gap in the spin excitation
spectra. He has given 23 invited talks at international conferences on superconductivity
since 1991.
