Thesis Defense in Pan 110
Speaker: Biqiong Yu, University of Minnesota
Subject: Synchrotron X-ray Scattering Studies of Complex Oxides
This is the public portion of Ms. Yu's thesis defense. Her advisor is Martin Greven.

Complex oxides, such as the copper-based high-temperature superconductors and the perovskite cobaltites, exhibit a vast range of properties and phases and are prominent research topics in condensed matter physics and materials science. Synchrotron X-ray techniques are powerful tools to study electronic and magnetic properties of materials. In my Thesis work, I present synchrotron X-ray scattering studies of four complex oxides: the cuprates HgBa2CuO4+d (Hg1201), La2-xSrxCuO4 (LSCO), and Nd2-xCexCuO4 (NCCO), and the cobaltite La0.5Sr0.5CoO3-d (LSCoO).
