Acoustic – Electromagnetic Transformation in Magnetic Nanofluids

Sokolov V.V., Moscow State University of Instrument Engineering and Computer Science, RU

Here is examined the acoustic – electromagnetic transformation accompanying the propagation of sound wave through a magnetic nanofluid.The magnetic nanofluid was placed in the cylindrical resonator. An external magnetic field was applied along an axis [...]

Ultrasound absorption in magnetic nanofluids

Sokolov V.V., Nadvoretskiy V.V., Moscow State University of Instrument Engineering and Computer Science, RU

Mechanisms of ultrasound absorption in magnetic nanofluids at the absence of external magnetic field are theoretically studied in the first part of the paper. The novel magnetodynamic mechanism of ultrasound absorption is introduced – it [...]

Dynamics of Magnetic Nanofluids with Frozen-in Magnetization

Sokolov V.V., Moscow State University of Instrument Engineering and Computer Science, RU

It was shown that in an ideal non-conducting magnetic nanofluid with frozen- in magnetization there are three types of waves: slow and fast magnetosonic waves and Alfvén -type wave. Alfvén -type wave propagating in non-conducting [...]
