Neutron Scattering Group

Welcome to the home page of the Neutron Scattering Group, a member of the Condensed Matter Physics and Materials Science Department at Brookhaven National Laboratory.

We use elastic and inelastic neutron scattering techniques to study cooperative phenomena in complex solids.  Much of our research is presently focused on transition-metal oxide compounds.  Current research topics include:

• High-temperature superconductivity
• Charge and spin order in doped Mott insulators
• Quantum and low-dimensional magnetism
• Relaxor ferroelectrics

Our experiments are typically performed on single crystal samples, many of which are grown and characterized at Brookhaven.   We perform our scattering experiments at the top neutron facilities in the world.  Within the U.S., we work regularly at the NIST Center for Neutron Research (NCNR) and at the High Flux Isotope Reactor (HFIR) at Oak Ridge National Laboratory (ORNL).  We look forward to doing experiments at the Spallation Neutron Source (SNS at ORNL), once it is completed and commissioned.  In collaboration with ORNL, Japan Atomic Energy Research Institute, JAERI, and other institutions, we are involved in the design and construction of new spectrometers. These include a Hybrid Spectrometer (HYSPEC) for the SNS, and the relocation of the US-Japan triple-axis spectrometer to cold-guide-4 at HFIR. There is also a  science alliance with NCNR.
