Magnetization Studies Of Oxides Related To The High Temperature Cuprate Superconductors , Zhaorong Wang

Retrospective Theses and Dissertations

An Oxford Instruments Faraday magnetometer, capable of operating in the temperature range between 1.5 K and 1000 K, and magnetic field range between 0 T to 8 T, with a sensitivity of 3x10[superscript]-8 cm[superscript]3G, was assembled and calibrated. The pumping station which supported this magnetometer was designed and built. Software for reducing the raw data and generating calibration files was written. The magnetic properties of several oxides related to the high temperature cuprate superconductors BaCuO[subscript]2+x, La[subscript]2CuO[subscript]4, Sr[subscript]2IrO[subscript]4, Sr[subscript]2RhO[subscript]4, Sr[subscript ...

Sub-Micron Scale Conduction Processes On Clean Surfaces , Kevin R. Kimberlin

Retrospective Theses and Dissertations

Fundamental electrical conductance measurement has been studied in-situ in two dimensions in the Ag/Si(111) system as a function of the incident adatom flux rate with a four probe technique. A conductance study in a three dimensional conical structure was also carried out with field emission techniques. Field emission is now well established and has been used in this case to characterize a novel geometry for use in flat panel displays to replace cathode ray tube monitors. For the two dimensional study on Ag/Si(111), the origin of conduction is still unclear, as both transport by means of ...
