Abstract
The effects of the magnitude and direction of a steady magnetic field on the propagation of longitudinal ultrasonic waves in N‐(p‐methoxybenzylidene)—p‐butylaniline have been investigated as a function of frequency and path length. The anisotropy of the measured ultrasonic attenuation is in good agreement with a theory of ultrasonic‐wave propagation in nematic liquid crystals based on micropolar continuum mechanics. The variation of the attenuation with frequency from 5–85 MHz is, however, inconsistent with present theories. Measurements of velocity and dispersion are also reported.
