Journal ArticleDOI
Thermal expansion of lT-TaS2 and 2H-NbSe2
TL;DR: The thermal expansion of the a and c axes of lT-TaS 2 and the a axis of 2H-NbSe 2 have been measured between 4 K and 360 K as discussed by the authors.
Journal ArticleDOI
Temperature dependence of sound velocities in TTF-TCNQ
TL;DR: In this article, a and b axis sound velocities in TTF-TCNQ single crystals are measured from 0-300K. The Young's modulus is larger in the a than in the b direction.
Journal ArticleDOI
Thermal expansion and velocity of ultrasonic waves in single phase YBa2Cu3O7−x
TL;DR: In this paper, the authors report resistivity, velocity of sound and thermal expansion measurements in single phase YBa 2 Cu 3 O 7−x with a 94 K superconductivity onset temperature, while no anomaly in the expansion coefficient was observed at that temperature.
Journal ArticleDOI
Elasticity and thermal expansion of 2HTaSe2 between 4K and 130K
TL;DR: In this article, sound velocity and attenuation and thermal expansion along the a and c axes in 2HTaSe2 have been measured from 4 to 140 K Contrary to an earlier prediction, no evidence is found for a phase change below 90 K, and it is concluded that the low temperature phase is orthorhombic Elastic anomalies are observed at To and Td, but not at Ti, and the attenuation is discussed in terms of the domain and discommensuration structure of TaSe2
Journal ArticleDOI
Elastic and thermal properties of CsNiF3
TL;DR: In this paper, a new anomaly was observed for the first time at a temperature of approximately 190 K in the thermal expansion coefficients both for in-plane and c-axis measurements.
