Growth And Electric Field Control Of Phase Separated Manganites, Hangwen Guo

Doctoral Dissertations

Perovskite Manganites have received numerous attentions due to exotic behaviors such as colossal magnetoreistance (CMR) and electronic phase separation (EPS). The purpose of my research is to answer fundamental questions about the growth properties of manganites and electric field control of the EPS properties.

Experimental study was conducted on controlling the growth mode of La0.7Sr0.3MnO3[Lanthanum Strontium Manganese Oxide] thin films using pulsed laser deposition. Different thin film morphology, crystallinity and stoichiometry have been observed depending on growth parameters. To understand the microscopic origin, the thermodynamic processes were theoretically analyzed and a growth diagram was …
