Muhetaer Aihaiti (Muhtar Ahart) runs the Brillouin Spectroscopy Laboratory at the Geophysical Laboratory. His research in high-pressure physics is aimed largely at problems in ferroelectrics, relaxor ferroelectrics, polymers, and novel materials.
Ronald E. Cohen's primary focus is the study of materials through first principles research including properties of materials under extreme conditions such as high pressure and temperature. His research is applied to topics and problems in geophysics and technological materials.
Washington, DC—New work from a research team led by the Geophysical Laboratory's Anat Shahar contains some unexpected findings about iron chemistry under high-pressure conditions, such as those likely found in the Earth’s core, where iron predominates and creates our planet’s life-shielding magnetic field.
Washington, DC—If you freeze any liquid fast enough, even liquid metal, it becomes a glass. Vitrified metals, or metallic glasses, are at the frontier of materials science research.
Producing materials by chemical vapor deposition (CVD) has become an important means of synthesis, in which high-energy molecular and atomic species generate a kinetically stable phase trapped in local energy minimum.
Iron makes up most of the Earth's core, which is very hot and exists under extreme pressures.
Washington, DC— As astronomers continue finding new rocky planets around distant stars, high-pressure physicists are considering what the interiors of those planets might be like and how their chemistry could differ from that found on Earth.
Washington, DC—Colossal magnetoresistance is a property with practical applications in a wide array of electronic tools including magnetic sensors and magnetic RAM.
Former Carnegie Summer Scholar at the Geophysical Laboratory, Viktor Rozsa, currently a graduate student at the University of Chicago, has been awarded a DOE-NNSA graduate fellowship.
