Study of Spin Configuration of Hexagonal Shaped Ferromagnetic Structures
… unique characterisation system and the study of spin configurations in hexagonal ferromagnetic structures. The characterisation system developed is able to perform in-situ magnetic imaging, structural modification and electrical transport measurement on ferromagnetic structures. For the latter, …

Electrical noise study of spin glass dynamics in mesocopic CuMn
The electrical resistance of the archetypal spin glass CuMn is surprisingly sensitive to small changes in the spin configuration. This enhanced sensitivity results from long-range electron quantum interference at low temperatures. Due to this effect, substantial resistance noise is produced by …

Electrical noise study of spin glass dynamics in mesoscopic copper manganese
The electrical resistance of the archetypal spin glass $\underline{\rm Cu}$Mn is surprisingly sensitive to small changes in the spin configuration. This enhanced sensitivity results from long-range electron quantum interference at low temperatures. Due to this effect, substantial resistance noise …

BLACK HOLES AND SOLUTION GENERATING TECHNIQUES
… field: it is possible to obtain an equilibrium configuration in many interesting cases, like a collection of collinear static black holes or a chain of accelerating black holes, by choosing appropriately the multipole parameters of the field. Then, we consider the expanding bubbles of nothing as …

Magnetic X-ray Reflectivity
… and the index of refraction, also the magnetic spin configuration can be chosen with arbitrary moment direction and magnitude by modifying the off-diagonal terms in the dielectric tensor. The magnetic optical constants, which determine the magnitude of the magnetic moments, are experimentally …

Micromagnetic simulations of magnetic exchange spring systems
… in high-performance permanent magnets, GMR spin devices, magnetic MEMS technology, and in magnetic data storage. We investigate the magnetic properties of MBE grown superlattices with alternating layers of magnetically hard rare earth-iron (DyFe2, ErFe2) and soft yttriumiron (YFe2) …

Structural and magnetic properties of erbium thin films and Er/Y superlattices
… not cause an interuption of the modulated Er spin order at the Er /Y interfaces. The CAM and basal plane spiral in these systems are coherent through the nonmagnetic yttrium interlayers. The primary differences between the magnetic behavior of bulk Er and both the films and superlattices are …

First-principles and Many-Body Methods: Implementations and Applications to Study Spintronic Materials
… are instrumental for the development of spintronic technology. Before we are able to engineer spintronic devices, it is necessary to understand the properties of materials from which spintronic devices are made, otherwise time and other resources will be wasted. In this thesis, we …

The nuclear spin dependence of the reaction of H3+ with H2 and the proposed spectroscopic investigation of HO2+
… its parent neutral, H$_2$, exist in two nuclear spin configurations, \emph{ortho} and \emph{para}, and yield unique spectral signatures that can be measured in the laboratory and in astronomical environments. Most importantly, these species have been found to be useful temperature probes of …

Studies of complexes derived from 5-acetylamino-1,2-benzoquinone 2-oxime and related ligands
… The diamagnetism of Co(5-Acqo)3 and the low spin configuration of Mn(5-Acqo)3.H2O are indicative of the strong field character of the ligand. COSY, H- and C n.m.r. studies have shown that Co(5-Acqo)3 is a mixture of facial and meridial isomers. For all complexes i.r. studies indicate the …
