Experimental investigation of the linear and nonlinear elastic properties of synthetic diamond single crystal

Experimental results of the propagation of bulk acoustic waves (10–200 MHz) in the synthetic diamond single crystal under the influence of uniaxial pressure and temperature have been presented. Obtained data of the second and the third order of elastic constants were used for calculation of the anisotropy of the acoustic waves propagation characteristics in diamond under the pressure application. The peculiarities of wave propagation have been discussed.
