“…In 1962, Jaccarino and Peter [183] predicted a FISC state when the external field is able to cancel the exchange field from the Fe moments. The high-field solid-state 77 Se NMR studies on (BETD-TSF) 2 FeX 4 FISCs have been interpreted as providing evidence for this Jaccarino-Peter compensation mechanism [166,177,179,180,182]. Fig.…”

“…Under ambient pressure, k-(BETD-TSF) 2 FeCl 4 shows a metal-insulator transition at T MI = 8 K. External applied magnetic fields reduce T MI and solid-state 77 Se NMR evidence for this transition has been found at 3.5 K when B 0 = 9.0 T [177], and 1.6 K when B 0 = 11.7 T [178]. At magnetic field strengths greater than 18 T, k-(BETD-TSF) 2 FeCl 4 undergoes field-induced superconductivity, FISC, reaching a maximum T c = 4.2 K at B 0 = 33 T, and with even greater magnetic fields T c returns to 0 K around B 0 = 45 T. Solid-state 77 Se NMR measurements were able to provide the first direct evidence of strong coupling between the conduction p electrons and the Fe d electron spins in k-(BETD-TSF) 2 FeCl 4 [166,177,179,180], and another FISC j-(BETD-TSF) 2 FeBr 4 [181,182]. This evidence has been used to elucidate the nature of the FISC state in these materials.…”

“…Before the theoretical prediction, Moldenhauer et al, reported that the localization of electrons occurs at the B and C sites whereas the electrons at the A and A′ sites are delocalized below T MI [12]. The 13 C-NMR study suggested the existence of two differently charged molecules below T MI [119,127]. Seo introduced intersite Coulomb interaction V, and he proposed that the localized charge would form a horizontal stripe [16].…”
