Anharmonicity of acoustic modes in vitreous TeO2

The temperature dependences between 298 and 358 K of the third-order elastic constants of vitreous TeO2 have been determined from measurements of hydrostatic and uniaxial pressure dependences of ultrasonic wave velocities. The results show that the vibrational anharmonicity of the long-wavelength ac...
