Recent research interests (in no particular order):
- Correlated Electron Systems: Compounds such as PrInAg2, Ce3Bi4Pt3, YbBiPt, YbNi2B2C, Yb14MnSb11, YbNi2Ge2, CeNi2Ge2, YbAgGe, YbPtIn, YbT2Zn20, CeT2Zn20 (T = transition metal) in which conduction band electrons interact strongly with each other and with local magnetic moments.
- Borocarbide Superconductors: Discovered in 1994, these compounds with general formula RNi2B2C, where R is a Rare Earth Element, display a rich variety of physical phenomena, including the coexistence of magnetic ordering and superconductivity. See the review article above.
- Magnesium Diboride: Discovered in January 2001, the superconductor MgB2 holds the record TC~40 K among all binary compounds, and has been subject of intense academic and applied research. Click here to see an interview with Paul Canfield on magnesium diboride superconductors, by the Institute for Scientific Information (ISI). Also see the review articles above.
- Quasicrystals: Certain compounds in the Al-Ga-Pd-Mn, Al-Ni-Co, R-Mg-Zn and RCd6 (R = Rare Earth element) systems can be grown in a well organized but non-periodic single grain structure, and consequently display unusual physical properties compared to true crystalline lattices.
- Metallic Spin-Glass Systems: Compounds such as (Gd1-xYbx)Ni2B2C, (Y1-xTbx)Ni2Ge2 and R3Mg51Zn46 (R = Rare Earth element) which are candidate model systems for testing spin-glass theories.
- Metamagnetic Systems: Compounds such as TbPtIn, TbNi2Ge2, DyAgSb2, HoNi2B2C, featuring rich magnetic phase diagrams with many possible arrangements of the antiferromagnetically ordered moments.
- Other Intermetallic Systems: Compounds such as RAgGe, RFe2Ge2, RCo2Ge2, RNi2Ge2, RAgSb2, RSb2, RAgBi2, RCo2, RAl2, RPtIn (R = Rare Earth element), and any other system with novel, interesting or unusual ground states, or whose physical properties have not yet been well established.
- Fe-As superconductors: Compounds such as RFeAs(O1-xFx), pure and doped AFe2As2 (R = Rare Earth element, A = Ca, Sr, Ba), featuring superconductivity at temperatures in excess of 50 K.
