1. Materials for Magnetic Recording Applications
Abstract : In the first part of this work, the influence of hydrogen on the structural and magnetic properties of Fe/V(001) superlattices was studied. The local structure of the vanadium-hydride layers was determined by extended x-ray absorption fine structure (EXAFS) measurements. READ MORE

2. Magnetic deflagration and detonation in crystals of nanomagnets
Abstract : In this thesis we cover the dynamics of the macro magnetic transformations (spin avalanches) in crystals of molecular nanomagnets, also known as magnetic deflagration and detonation.Taking a single-molecule Hamiltonian, we calculate the dependence of Zeeman energy and the activation energy as a function of an external magnetic field at different angles relative to the easy axis of the crystal.

3. Studies of magnetic multi-core nanoparticles for biomedical applications
Abstract : In recent years, there has been growing interest in using magnetic multi-core nanoparticles in biomedical applications, and particularly in bioseparation and biosensing. In this thesis, two computer simulation techniques have been implemented to study the magnetic response of these particles, and a microfluidic platform has been fabricated to manipulate bio-functionalized magnetic particles in suspension for immunoassays.

4. Assessing Holocene and late Pleistocene geomagnetic dipole field variability
Abstract : Palaeomagnetic studies of continuous geological archives and archaeological artefacts are required to reconstruct geomagnetic field changes beyond the range of historical observations. In this thesis I assess the reliability of sedimentary palaeomagnetic data and Holocene dipole field reconstructions. READ MORE

5. Magnetic dipole excitations in even-even nuclei
Abstract : The properties of K(pi) = 1+ states in deformed even-even rare-earth nuclei have been investigated within the Quasiparticle Random Phase Approximation (QRPA). The B(M1) spectrum and the differential cross section for electron scattering have been calculated and are seen to be consistent with the interpretation that the experimental 1+ states first considered to be a scissors mode, actually correspond to slightly collective states with the main proton components coming from positive parity proton states.
