Growth And Characterization Of Ferromagnetic Lcmo And Ferroelectric Pzt Thin Films

Addresses the phenomena of colossal magnetoresistance (CMR) and magnetic properties associated with the incorporation of ferromagnetic (FM) lanthanum calcium manganese oxide (LCMO) (in thin film and nanoparticle form) into Si (silicon)-based systems. Discusses the growth FM lanthanum calcium manganese oxide (LCMO) thin films by pulsed laser deposition (PLD) on Si substrates by using a high conducting barrier layer of titanium nitrogen (TiN). Uses magnesium oxygen (MgO) and strontium titanium ozone (SrTiO3) films as intermediate layers between LCMO and TiN layers in order to prevent interfacial interactions with oxygen and to achieve epitaxial growth of LCMO films. Investigates the growth, characterization, and electrical properties of ferroelectric (FE) lead zirconium titanate (PZT) thin films on Si-based systems. Embeds well-separated non-interacting LCMO nanoparticles in an insulating medium using PLD.
