Magneto-acoustic attenuation in AuSb2
Solid State Communications, 1974Abstract Quantum oscillations in the ultrasonic attenuation in AuSb2 were studied as a function of temperature, magnetic field and crystal orientation. The effective masses of the carriers associated with the F5 and F6 oscillations were measured in a (110) plane.

Magneto-Acoustic Interaction in Mercury
The Journal of the Acoustical Society of America, 1969The magnetically induced acoustic absorption coefficient in liquid mercury has been measured around its inverse relaxation frequency using an on-line computer and magnetic fields of up to 10 kg. The hybrid computer-operated differential measuring system took between 2560 and 25 600 experiments per run.

The magneto-acoustic emission (invited)
Journal of Applied Physics, 1993When cycling a hysteresis loop, bursts of high frequency ultrasonic waves are emitted. This general phenomenon, which must not be confused with the classical magnetostrictive effect at twice the cycling frequency, is called the magnetoacoustic emission (MAE). By using literature and authors’ results, qualitative and quantitative, the authors review the

Nonlinear magneto-acoustic dispersive waves
Astrophysics and Space Science, 1977The multiple time scale method is applied to investigate the nonlinear magneto-acoustic dispersive waves in a collisional plasma. Whereas in the absence of collisions these waves are modulationally stable, the collisions render them modulationally unstable.

Magneto-acoustic imaging by continuous-wave excitation
Medical & Biological Engineering & Computing, 2016The electrical characteristics of tissue yield valuable information for early diagnosis of pathological changes. Magneto-acoustic imaging is a functional approach for imaging of electrical conductivity. This study proposes a continuous-wave magneto-acoustic imaging method.

Physics Letters, 1963
A solution is obtained for the induced magnetic field caused by the propagation of sound waves through an electrically conducting medium in a direction parallel to the original magnetic field. The equation of continuity is introduced into the coupled equations for the hydrodynamic flow and the electromagnetic field. (R.E.U.)

Magneto-Acoustic Waves in a Plasma
The Physics of Fluids, 1963The propagation of plane magneto-acoustic waves in a highly conducting plasma is examined, and the results are applied to magneto-acoustic pulsations of a cylindrical configuration. (C.E.S.)

Experimental observations of magneto-acoustic fields
The Journal of the Acoustical Society of America, 1983Experimental observations of electric fields induced in salt water by acoustic waves in a resonant cavity interacting with a strong constant magnetic field are described. The fields are found to behave linearly with the constant magnetic field strength as well as with the acoustic field strength as predicted theoretically.

Physical Review, 1941
In recent years considerable interest has developed'1 among chemists and physicists in the determination of the velocity of sound in liquids by means of high fre¬quency sound waves. These measurements are valuable for our knowledge of molecular properties.

Nonlinear magneto-acoustic waves in ferromagnets
Journal of Applied Physics, 1996The nonlinear coherent interaction of a high-frequency acoustic wave pulse with a magnetically ordered medium is studied theoretically. We consider both microscopic and phenomenological theories of the formation of nonlinear magneto-acoustic waves in a ferromagnet.
