Hamiltonian and Lagrangian Dynamical Matrix Approaches Applied to.
The study of collective spin excitations in magnetically ordered materials so-called spin waves and the associated quasi-particles---magnons has a successful history of more than 60 years.
Nano Letters | Vol 16, No 1 - ACS Publications.
A general theory of collective spin-wave excitations in a two-dimensional array of magnetic nanodots coupled by magnetodipolar interaction is developed. The theory allows one to analytically.
New pathways towards efficient metallic spin Hall spintronics.
In this paper we review the full band structures of collective spin excitations ranging from zero to large wave vectors k [36, 89] as they are key for applications in magnonics. Our discussion addresses the prototypical insulating ferrimagnet Cu 2 OSeO 3 as at this point it offers the smallest spin-wave damping [ 91 ] and has shown the. Magnonics addresses the dynamic excitations of a magnetically ordered material. These excitations, referred to as spin waves and their quanta, magnons, are a powerful tool for information transport.

Open-shell nanographenes have emerged as privileged testing ground to study carbon-based magnetism and to explore potential applications of organic molecules in spintronics and quantum technologies. 1, 2 However, the atomically precise preparation of such nanostructures is challenging due to the high reactivity of these graphene derivatives with radical character under ambient conditions. We describe both the status of theory and recent inelastic light scattering experiments addressing the most important issues; the quantization of localized spin waves due to the in-plane.

Mesoscale strategies of collective transport on deformable liquid interfaces. Transport at interfaces is crucial in multiple areas of physics and biology and is observed across a wide range of length scales. In the strategies used in such dynamics, the role of hydrodynamic interactions, interface deformations, and the presence of other agents. News amp; Events Neues aus dem Institut Newsletter Vortrage.

Spin Hall effects interconvert spin- and charge currents due to spin-orbit interaction, which enables convenient electrical generation and detection of diffusive spin currents and even collective spin excitations in magnetic solids. Here, we review recent experimental efforts exploring efficient spin Hall detector materials as well as new approaches to drive collective magnetization dynamics.
