Dynamics of ethylene groups and hyperfine interactions between donor and anion molecules in $\lambda$-type organic conductors studied by ${}^{69,71}$Ga-NMR spectroscopy

N. Yasumura, T. Kobayashi, H. Taniguchi +2

We present the results of ${}^{69,71}$Ga-NMR measurements on an organic antiferromagnet $\lambda$-(BEDSe-TTF)${}_2$GaCl${}_4$ [BEDSe-TTF=bis(ethylenediseleno)tetrathiafulvalene], with comparis…
