Charge imbalance in $\lambda$-(BETS)${}_2$GaCl${}_4$ and their interplay with superconductivity

Olga Iakutkina, Ece Uykur, Takuya Kobayashi +3

The two-dimensional organic superconductor $\lambda$-(BETS)${}_2$GaCl${}_4$ exhibits pronounced charge fluctuations below $T\approx 150$~K, in contrast to the sibling compound $\kappa$-(BETS)$_2…
