Magnetic and electric properties of multiferroic thin-film manganites
K.U.Leuven
Abstract: The PhD project aims at investigating the coupling between electric and magnetic order parameters in multiferroic complex oxide thin
films. These materials exhibit simultaneously ferroelectric and magnetic ordering. The two ferroic order parameters are strongly entangled by a
magneto-electric coupling, allowing the reversal of the ferroelectric polarization by applying a magnetic field or the control of the magnetic order
parameter by an electric field. This unique property makes multiferroic materials very good candidates for designing tunable multifunctional
spintronic devices. The coexistence of ferroelectricity and magnetic order wasfound in rare earth manganites RMnO3.
The PhD research project can be divided into three parts.
The first part involves development and realization of the preparation of the thin film manganite (YMnO3, YbMnO3, SmMnO3, HoMnO3, TbMnO3
and GdMnO3) samples.
The second part involves detailed structural, magnetic and electric characterization of the th

Visualization and localisation of defects by nonlinear elastic wave spectroscopy techniques
K.U.Leuven
Abstract: The doctoral research will aim at developing experimental and numericaltechniques for nonlinear ultrasonic non-destructive testing and
evaluation (NDT&E). As part of the research and dissertation, several nonlinearelastic wave spectroscopy (NEWS) techniques will be developed
and further refined. NEWS focuses on methodologies to increase the detection sensitivity of material microdamage through an amplitude dependent
analysis of key material parameters. The information acquired using the NEWS methods will be further exploited to visualize zones of deterioration.
Innovative implementations of experimental NEWS based techniques will be considered to enhance the reliability and accuracy of microdamage
detection by implementing selective-focusing techniques based on time-reversal andtomographic approaches and to improve the detection of
multiple damagedregions by signal processing techniques.
The wave equation in a nonlinear #or damaged- elastic medium, will be studied both from a nu

Investigating the effect of W on the solid phase reaction of nickel silicides
K.U.Leuven
Abstract: Silicides, i.e. compounds between a metal and silicon, formed through the reaction of a metal film with a Si substrate, are often used as
electrical contact layers in semiconductor devices. As device dimensions are drastically decreasing, the requirements for these silicide thin films
