Thermal expansion of organic superconductor κ-(D₄-BEDT-TTF)₂Cu{N(CN)₂}Br. Isotopic effect
Linear thermal expansion coefficient (LTEC) of single crystal κ-(D₄-BEDT-TTF)₂Cu[N(CN)₂]Br was studied across the crystal layers in the temperature range 2–290 K using the method of precise capacitive dilatometry. Below Tc = 11.6 K the LTEC of the sample had a small negative value, which is apparent...
