Thermal expansion of niobium dichalcogenide in the vicinity of low-temperature phase transitions — •Vladimir Ibulaev, Victor Eremenko, Valentyna Sirenko, and Mikhail Shvedun — Institute for Low Temperature Physics, 61103 Kharkov, Ukraine

X-ray and dilatometric measurements were performed on charge-density-wave superconductor 2H-NbSe₂ in the temperature range 1.5÷300 K. Anomalies of thermal expansion in the vicinity of CDW (32.5K) and superconducting (7.2K) transitions are discussed regarding structure evolution.
