    Non magnetic anion substitution in (TMTSF)<sub>2</sub>ClO<sub>4</sub>: Consequences on the superconductivity

    No full text
    Non magnetic impurities substitution is a method to check the microscopic origin of superconductivity. In (TMTSF)2_{2}ClO4_{4}, we substitute a small fraction of the ClO4_{4} anions by ReO4_{4}. The anion ordering temperature is shown to be unaffected by alloying in the explored range 0-3.1%. However, the critical temperature is strongly reduced with increased residual resistivity obtained through alloying and/or increased speed of cooling. Our results are compatible with an unconventional superconductivity in the Bechgaard salts. Key words. Bechgaard salts – unconventional superconductivity – alloys
