Electric And Magnetic Properties Of High-tc Oxide Superconductors

The theories of conventional super conductivity arernreviewed. We have investigated the electric and magneticrnproperties using differentrnseebeck effect measurement,rnexperimental techniques such asrnHall effect measurement, andrnstandard four - probe method.rnBased on the experiment, transitionrncarrier concentration are estimated. Ourrnmetallic above transition temperature.rntemperature andrnsamples behavernTo explain thernsuperconducting mechanism, exciton mechanism is discussed withrnrespect to ABB (Allender, Bray and Bardeen) model: - a thinrnmetallic layer on a semiconductor surface. Using computerrnsimulation, we observe that our results agree with theoreticalrnproposed exciton mechanism model (ABB)
