The technique, known as x-ray photon correlation spectroscopy (XPCS), available at NSLS-II’s Coherent Soft X-ray scattering ( CSX) beamline, allowed the researchers to look at how the material changed at the nanoscale-on the order of billionths of a meter. Roopali Kukreja (L), the lead author of the paper with Andi Barbour (R), CSX beamline scientist, work closely together while setting up the next set of measurements. However, studying this arrangement and how it changes under different conditions required the scientists to be able to look at the magnetite at a super-tiny scale. “This electronic arrangement is related to why we believe magnetite becomes an insulator,” said Kukreja. To understand the metal-insulator transition of magnetite, the researchers needed a way to watch how the arrangement of the electrons in the material changed with the alteration of temperature. This ordering of electrons is important because it dictates a material’s properties, for example its conductivity. In any material, there is a specific arrangement of electrons within each of its billions of atoms.

For the published study, the researchers’ goal was to see how the magnetite changed from insulator to metallic at the atomic level as it got hotter. In the case of magnetite, temperature can change whether the material is a conductor or insulator. If a material is a good conductor of electricity, it is usually metallic, and if it is not, it is then known as an insulator. One such property is electrical conductivity, which determines whether a material is metallic or an insulator. “Correlated materials have interesting electronic, magnetic, and structural properties, and we try to understand how those properties change when their temperature is changed or under the application of light pulses, or an electric field” said Roopali Kukreja, a UC Davis professor and the lead author of the paper. Department of Energy (DOE) Office of Science user facility located at Brookhaven National Laboratory, has unique features that allow the technique to be applied with stability and control over long periods of time. The researchers from the University of California Davis published their paper in the journal Physical Review Letters. UPTON, NY – By using an x-ray technique available at the National Synchrotron Light Source II (NSLS-II), scientists found that the metal-insulator transition in the correlated material magnetite is a two-step process.
