Ph.D., 1998 - Tulane University
Our research is centered on the synthesis and characterization of bulk and thin film materials, with an emphasis on magnetic systems with applications in energy and electronics. Our current areas of research are: (i) magnetocaloric materials and (ii) highly spin-polarized alloys.
Materials the exhibit large room-temperature magnetocaloric effects are sought for solid state cooling applications. Magnetic refrigeration has many advantages over conventional cooling (compressed gas) technologies: it is more energy efficient and environmentally friendly. This project is funded by Basic energy Sciences, Department of Energy.
The development of half-metallic (spin-polarized) materials is needed for spintronics applications – the evolution of electronics in which devices utilize both the charge and the spin of the electron. This project is funded by the National Science Foundation.
We are also interested in solid-oxide fuel cell materials (with Montana State University), ferromagnetic shape-memory alloys and magnetic nanocomposites (with Southern Illinois University), and thermoelectric materials and superconductors (with collaborators at LSU).
Our lab facilities include: (i) a pulsed laser deposition system; (ii) a magnetic properties measurement system (MPMS); (iii) an AC/DC magneto-optic Kerr effect (MOKE) system; and (iv) an x-ray diffraction (XRD) system. Other facilities in the department include bulk synthesis systems (arc-melting, RF) and physical properties measurement systems (PPMS). Single crystal XRD, TEM, SEM, EDX, and WDS are also available on the LSU campus.
