dc.description.abstractWe report on the growth and characterization of strontium ruthenate (214) (Sr2RuO4) and strontium rhodate (214) (Sr2RhO4) in efforts to test their agreement with Landau-Fermi liquid theory using optical measurements. We begin by reviewing the theory of Landau-Fermi liquids and the frequency and temperature dependent conductivities. We review existing work on both Sr2RuO4 and Sr2RhO4 including evidence of agreement with Landau-Fermi liquid theory. We also describe optical floating zone crystal growth and the exact procedures we used to prepare samples of both Sr2RuO4 and Sr2RhO4 via optical floating zone. The resulting Sr2RuO4 crystals were characterized using AC susceptibility measurements and Sr2RhO4 by powder diffraction, single crystal diffraction, and SQUID magnetization measurements. Finally, early optical reflectivity measurements at low temperatures are presented.en_US

dc.description.layabstractCrystals of Sr2RuO4 and Sr2Rho4 were grown by the author in an effort to study changes of their resistivity with varying temperature and frequency at low temperatures. The crystals were characterized using a variety of x-ray and other techniques, so as to measure their purity. Past work on these materials is discussed and analyzed. Preliminary measurements of the resistivity are presented.en_US
