Spin–orbit-driven ferromagnetic resonance [PDF]

Nature Nanotechnology, 2011
Ferromagnetic resonance is the most widely used technique for characterizing ferromagnetic materials. However, its use is generally restricted to wafer-scale samples or specific micro-magnetic devices, such as spin valves, which have a spatially varying magnetization profile and where ferromagnetic resonance can be induced by an alternating current ...

Dynamical Interactions and Mass Loss within the Uranian System

The Planetary Science Journal, 2023
The origin and evolution of planetary rings and moons remains an active area of study, particularly as they relate to the impact history and volatile inventory of the outer solar system.

15:1 Resonance effects on the orbital motion of artificial satellites [PDF]

Journal of Aerospace Technology and Management, 2011
The motion of an artificial satellite is studied considering geopotential perturbations and resonances between the frequencies of the mean orbital motion and the Earth rotational motion.

Orbital Resonances in the Vinti Solution [PDF]

, 2016
The Vinti Solution offers a more accurate model than the two-body problem as an orbital propagator. Unfortunately, the Vinti solution contains small divisors near orbital resonances in the perturbative terms of the Hamiltonian, which lead to inaccurate ...

Interaction of an Archimedean spiral structure with orbital angular momentum light

New Journal of Physics, 2018
Complementing the research of surface plasmon polariton vortices for Archimedean spiral structures grooved in gold platelets, we here study the analogous positive structure of an Archimedean spiral consisting of bent gold nanorods. We consider spirals of

Secondary resonances of co-orbital motions [PDF]

, 2007
The size distribution of the stability region around the Lagrangian point L-4 is investigated in the elliptic restricted three-body problem as the function of the mass parameter and the orbital eccentricity of the primaries.

Census of transient orbital resonances encountered during binary inspiral

, 2013
Transient orbital resonances have recently been identified as potentially important to the inspiral of small bodies into large black holes. These resonances occur as the inspiral evolves through moments in which two fundamental orbital frequencies, Ω ...

“Low‐Positive” MOG‐IgG Cases Among Adults With a First Event Suggestive of Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To determine the prevalence and clinical characteristics of patients with “low‐positive” (LP) MOG‐IgG (titres 1:160–1:320) among adults with a first demyelinating event (FDE) suggestive of multiple sclerosis (MS). Methods From the Barcelona CIS inception cohort, we included adult patients with serum collected ≤ 6 months from the FDE.

Numerical investigation of Fano resonances in metamaterials with electric asymmetry [PDF]

, 2011
The excitation of high quality factor asymmetric Fano-type resonances on a double layer metafilm structure is investigated through numerical simulation. The paper demonstrates that it is possible to design simple structures capable to sustain a very high

Orbital Resonances Around Black Holes

Physical Review Letters, 2015
We compute the length and timescales associated with resonant orbits in the Kerr Metric for all orbital and spin parameters. Resonance induced effects are potentially observable when the Event Horizon telescope resolves the inner structure of Sgr A*, space-based gravitational wave detectors record phase-shifts in the waveform during the resonant ...
