Acoustical properties of B-modification smectic liquid crystals in static magnetic fields
Lagunov A.S., Balandin V.A.
The temperature dependence of ultrasound velocity is studied for different orientation angles of the magnetic field and wave vector, A change is observed in the sign of anisotropy of ultrasound velocity in comparison with the nematic phase. Measurements are used as a basis for calculations of the temperature dependence of elastic constants.
