Thesis Advisor: Prof. P. A. J. de Groot
Thesis title: Engineering the magnetic properties of epitaxial RE-Fe2 Laves
phase alloy and multilayer films
The project was conducted in collaboration with Oxford MBE Laboratory (UK),
and funded by D.E.R.A (Defense Evaluation and Research Agency), recently
renamed QinetiQ, and based at Farnborough (UK).
I investigated the magnetic properties and transport
characteristics of multilayers of the cubic Laves Phase DyFe
2 and YFe
2. The
samples were produced by Oxford MBE Laboratory (UK). Magnetic measurements
were made using a 12T Vibrating Samples Magnetometer, and also a 6T SQUID.
Magnetotransport measurements were performed on a 16T rig, and on a 30T
magnet at the High Magnetic Field Laboratory (Grenoble, France). In
addition, Neutron reflectometry measurements were conducted at the
International research Centres: ISIS in UK and the Laue Langevin Laboratory
(ILL) in France. The neutron reflectometry technique enabled to determine the magnetic configurations
of the superlattices. It has been highlighted that DyFe
2-YFe
2 multilayers
witness extra magnetic moment due to the formation of magnetic exchange
springs in the YFe
2 layers.
The main achievements of the PhD project are:
modelling
of magnetic
exchange springs in the YFe2 layers,
tailoring coercive field by adjusting the
thickness of DyFe2 and YFe2,
engineering multilayer films with negative coercivity,
and
observe GMR up to 30%.

Maitrise de Physique Fondamentale (equivalent to B.Sc. after The
British Council)
Université Denis Diderot - Paris (France)
Tutor: Prof. Alain Touati
I spent the final year of my degree at the University of York (UK), as part
of the European Exchange program (Erasmus).
3rd Year Project: The project
involved the study of a GMR-structure placed under microwave radiation as a
function of an applied magnetic field. A granular ferromagnetic thin film
structure was investigated to test the feasibility of measuring Giant magneto-Impedance. A significant
amount of time was spent on eliminating stray field earthing effects.
