Presentation Transcript

  1. Synthesis and Characterization of Solid Oxides Exhibiting Nanostructured Magnetic LatticesShiou-Jyh Hwu, Clemson University, DMR-0322905 We have been exploring extended solids that contain magnetic nano-structures for they, like molecular magnets, have promising device applications as quantum memory materials for quantum computing. The major emphasis of our research activities is to investigate the chemistry of extended solids that contain low-dimensional magnetic clusters, chains and sheets of transition metal oxides. Using molten-salt methods, sizable single crystals can be grown for the investigation of structure/property correlation to reveal the spin coupling behaviors in confined magnetic lattices. Magnetization versus field hysteresis loops for single crystals of RbNa3Fe7(PO4)6 at 5K. The loops show steps, characteristic of quantum tunneling ofmagnetization (QTM) . W. Queen and S.-J. Hwu, Chem. Comm., to be submitted 2005.

  2. Synthesis and Characterization of Solid Oxides Exhibiting Nanostructured Magnetic LatticesShiou-Jyh Hwu, Clemson University, DMR-0322905 Outreach: Education: Three undergraduates (R. Britt, K. Pott, P. West), one faculty (Dr. C. T. Eagle), and seven graduate students (G. Becht, E. A. Clark, W. Queen, S. Ranmohotti, A. Siegfried, L. Wang, M. Williams), and one postdoc (X. Mo) have been working in the PI’s lab. Britt, Eagle, and Pott from Appalachian State University joined the group for summer research. Dr. Eagle will continue to collaborate with the PI in solid state research. She is currently in the process of setting up a reseach lab at Appalachian State, and Britt and Pott will continue to study their undergraduate research under her. West graduated from Clemson in May, 2005, and will continue his graduate study in the PI’s group starting in Spring 2006. The PI presenting a seminar on “Smart Materials” to local high school students, including the group of Junior Academy of Science students at the Daniel High. Students experienc-ing the operation of a heat pump made from a thermoelectric device. With the PI looking on, students participate in a group effort to unravelthe pre-shaped memory metal.
