Nutation spin waves in ferromagnets [PDF]
Physical review B, 2021 Magnetization dynamics and spin waves in ferromagnets are investigated using the inertial Landau-Lifshitz-Gilbert equation. Taking inertial magnetization dynamics into account, dispersion relations describing the propagation of nutation spin waves in an ...

Dispersion relation of nutation surface spin waves in ferromagnets [PDF]
, 2021 Inertia effects in magnetization dynamics are theoretically shown to result in a new type of spin waves, i.e. nutation surface spin waves, which propagate at terahertz frequencies in in-plane magnetized ferromagnetic thin films.

Emerging magnetic nutation [PDF]
The European Physical Journal B, 2021 Nutation has been recognized as of great significance for spintronics; but justifying its presence has proven to be a hard problem. In this paper we show that nutation can be understood as emerging from a systematic expansion of a kernel that describes the history of the interaction of a magnetic moment with a bath of colored noise.

Influence of intersublattice coupling on the terahertz nutation spin dynamics in antiferromagnets [PDF]
Physical review B, 2021 Spin nutation resonance has been well-explored in one-sublattice ferromagnets. Here, we investigate the spin nutation in two-sublattice antiferromagnets as well as, for comparison, ferrimagnets with inter-and intra-sublattice nutation coupling.

The Viscous and Ohmic Damping of the Earth's Free Core Nutation
Journal of Geophysical Research - Solid Earth, 2021 The cause for the damping of the Earth's free core nutation (FCN) and the free inner core nutation eigenmodes has been a matter of debate since the earliest reliable estimations from nutation observations were made available.

Mathematic Modelling and Numerical Analysis for a Novel Inner-Type Nutation Magnetic Drive
Energies, 2020 This paper presents an inner-type of magnetic gears for non-contact driving, based on the nutation gearing principle. An improved three-dimensional analytical model, based on the magnetic vector potential of rectangular permanent magnets, via the ...

Experimental model for the description of the behaviour of a 9-mm projectile at a target
Forensic Sciences Research, 2021 Analysis of crime scenes involving single-fire-gun projectiles requires the determination of the direction of arrival of a projectile at the target and other factors to reconstruct events.

Nutation in antiferromagnetic resonance [PDF]
, 2020 The effect of inertial spin dynamics is compared between ferromagnetic, antiferromagnetic and ferrimagnetic systems. The linear response to an oscillating external magnetic field is calculated within the framework of the inertial Landau--Lifshitz ...
