The dissipation of magneto-acoustic waves

open access: yesComputers & Mathematics with Applications, 1994
The propagation of magneto-acoustic waves in a thermally conducting isothermal atmosphere, in the case of dominant magnetic field, is studied. It is shown that the atmosphere may be divided into two distinct regions: the lower region where the motion is approximately adiabatic, and the upper region where the solution decays with the altitude to a ...

Opto-magnonic crystals: optical manipulation of spin waves [PDF]

open access: yes, 2019
It is well-recognized in condensed matter physics that structural and magnetic properties are intimately connected; thus controlling structure has been a successful route to controlling material properties.

Localised excitations in long Josephson junctions with phase-shifts with time-varying drive [PDF]

open access: yes, 2012
In this project, we consider a variety of ac-driven, inhomogeneous sine-Gordon equations describing an infinitely long Josephson junctions with phase shifts, driven by a microwave field.

Magneto-acoustic coupling: Physics, materials, and devices

open access: yesActa Physica Sinica
Acoustic wave in solid has two modes of propagation: the bulk acoustic wave (BAW), which propagates inside solid in the form of longitudinal or transverse wave, and the surface acoustic wave (SAW), which is generated on the surface of solid and propagates along the surface.
