Spin waves in the collinear antiferromagnetic phase of Mn5Si3

Jan Persson

By combining two independent approaches, inelastic neutron-scattering measurements and density-functionaltheory calculations, we study the spin waves in the collinear antiferromagnetic phase (AFM2) of Mn5Si3. We obtain its magnetic ground-state properties ...

Engineering atomic-scale magnetic fields by dysprosium single atom magnets

Harald Brune, Tobias Bilgeri

Atomic scale engineering of magnetic fields is a key ingredient for miniaturizing quantum devices and precision control of quantum systems. This requires a unique combination of magnetic stability and spin-manipulation capabilities. Surface-supported singl ...

Effective properties and eddy current losses of soft magnetic composites

Xiaotao Ren

This paper presents a semi-analytical homogenization model for Soft Magnetic Composites (SMCs), providing the effective magnetic behavior and the level of Eddy Current (EC) losses. Both linear and nonlinear magnetic behavior are considered. A magnetic circ ...

Correlation-Driven Transient Hole Dynamics Resolved in Space and Time in the Isopropanol Molecule

Christoph Bostedt, Andrew Daniel Bonnar Clark

The possibility of suddenly ionized molecules undergoing extremely fast electron hole (or hole) dynamics prior to significant structural change was first recognized more than 20 years ago and termed charge migration. The accurate probing of ultrafast elect ...

Fabrication and applications of AuAg alloy metasurfaces and hybrid metal dielectric nanoantennas

Debdatta Ray

The most prevalent materials used in the field of plasmonics are Au and Ag. However, for the past few years, the plasmonic community has also been looking for alternative materials that have lower losses than Au and higher stability than Ag. This thesis is ...

On the non-existence of stepped-pressure equilibria far from symmetry

Joaquim Loizu Cisquella

The Stepped Pressure Equilibrium Code (SPEC) (Hudson et al 2012 Phys. Plasmas 19 112502) has been successful in the construction of equilibria in 3D configurations that contain a mixture of flux surfaces, islands and chaotic magnetic field lines. In this m ...
