Nutation spin waves in ferromagnets

, 2022
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 ...

Plant nutation relies on steady propagation of spatially asymmetric growth pattern. [PDF]

Quant Plant Biol
Nutation is one of the most striking and ubiquitous examples of the rhythmic nature of plant development. Although the consensus is that this wide oscillatory motion is driven by growth, its internal mechanisms remain to be fully elucidated. In this work,

Spin pumping at terahertz nutation resonances

, 2021
We investigate spin pumping current injected by the nutation resonances of a ferromagnet (FM) or an antiferromagnet (AFM) into an adjacent metal. Comparing the dc spin pumping current between the normal precession and the nutation resonances, we find ...

Long-period nutational-precessional motions of the instantaneous Earth rotation pole

Учёные записки Казанского университета: Серия Физико-математические науки, 2020
The influence of the rotational regime on real long-period nutational-precessional motions of the instantaneous pole of the Earth’s rotation is considered. The solar magnetospheric (through changes in the angular velocity of rotation) mechanism of action

Biomechanical analysis of sacroiliac joint motion following oblique-pulling manipulation with or without pubic symphysis injury

Frontiers in Bioengineering and Biotechnology, 2022
Background: Oblique-pulling manipulation has been widely applied in treating sacroiliac joint (SIJ) dysfunction. However, little is known about the biomechanical mechanism of the manipulation.

Basic Earth's Parameters as estimated from VLBI observations

Geodesy and Geodynamics, 2017
The global Very Long Baseline Interferometry observation for measuring the Earth rotation's parameters was launched around 1970s. Since then the precision of the measurements is continuously improving by taking into account various instrumental and ...

The geometry of larmor nutation [PDF]

, 2002
The nutation accompanying the well-known Larmor precession discussed with respect to an inertial frame in an earlier paper is now considered in the rotating Larmor frame where the precession is absent and the nutation is therefore fully emphasized. It is

On the coupling between magnetic field and nutation in a numerical integration approach

, 2011
Nutation amplitudes are computed in a displacement field approach that incorporates the influence of a prescribed magnetic field inside the Earth's core. The existence of relative nutational motions between the liquid core and its surrounding solid parts
