    • Magnetic and Electronic Phenomena in Oxide Interfaces, Thin Films and Heterostructures 

      Porter, Stephen
      The miniaturisation and reduction of power consumption in modern integrated circuitry and active compo- nents such as sensors and memory demands the development of novel materials. These materials must not only have ...

    • Magnetic and transport properties of magnetite based nanostructures 

      Wu, Han-Chun (Trinity College (Dublin, Ireland). School of Physics, 2009)
      In this thesis, we investigate the magnetic and transport properties of magnetite based nanostructures. We in particular investigate the magnetization and surface Verwey transition of magnetite thin film, interlayer ...

    • Magnetic barcodes in molecular medicine 

      Byrne, Fiona N. (Trinity College (Dublin, Ireland). School of Physics, 2010)
      The need for faster and more sensitive diagnostic systems for the early detection of many life-threatening diseases is the driving force behind the work in this thesis. A lab-on-a-chip prototype device incorporating a ...

    • Magnetic field effects on electrodeposition and the properties of electrodeposited nickel and nickel-copper 

      O'Reilly, Cora (Trinity College (Dublin, Ireland). School of Physics, 2004)
      The association of magnetism and electrodeposition is studied from two separate perspectives. Firstly the effect of an applied magnetic field on the deposition process and secondly the production of magnetic materials by ...

    • Magnetic field effects on the electrodeposition and electrodissolution of copper 

      Hinds, Gareth (Trinity College (Dublin, Ireland). School of Physics, 2001)
      The effect of a static magnetic field on the electrodeposition and electrodissolution of copper in acidified copper sulphate solution was investigated. The primary effect of the field was to increase the rate of mass ...

    • Magnetic semiconductors for spin electronics 

      Alaria, Jonathan (Trinity College (Dublin, Ireland). School of Physics, 2010)
      The development of the relatively new field of spin electronics is based on the possibility of manipulating the spin of the electron through a structure. If one aspect is to develop new device architecture to inject, ...

    • Magnetism in dilute magnetic oxides and related materials 

      Gunning, Robert Denis (Trinity College (Dublin, Ireland). School of Physics, 2007)
      The work in this thesis is focussed on the magnetic properties of dilute ferromagnetic semiconducting oxides and related materials. Since the first report of unexpected room temperature ferromagnetism in anatase and rutile ...

    • Magnetization processes and low frequency fluctuations in micromagnetic structures 

      Diao, Zhu (Trinity College (Dublin, Ireland). School of Physics, 2010)
      The study presented in this thesis is concerned with low frequency fluctuations in magnetic systems. Three different systems were investigated. The first system is (CoFe/Pt)n multilayers patterned into micrometer scale ...

    • Manipulating atoms using scanning probe microscopy 

      Norris, Andrew Christopher (Trinity College (Dublin, Ireland). School of Physics, 2009)
      Manipulating species using Scanning Probe Microscopy (SPM) is an important discipline in the field of bottom-up fabrication, which facilitates nano-mechanics and electron dynamics investigations. Previous low temperature ...
