The NMR of 57Fe was detected for the first time in zero external field at 1.5 K in a isotropically enriched and magnetically oriented powder sample of the octanuclear iron(III) cluster, Fe8. Eight well resolved lines, each about 100 kHz wide, were observed in the frequency range 63.1–72.4 MHz confirming the total lack of symmetry of the Fe8 molecule. The resonance frequency of the different lines are analyzed in terms of the hyperfine interactions.

Abstract

The NMR of 57Fe was detected for the first time in zero external field at 1.5 K in a isotropically enriched and magnetically oriented powder sample of the octanuclear iron(III) cluster, Fe8. Eight well resolved lines, each about 100 kHz wide, were observed in the frequency range 63.1–72.4 MHz confirming the total lack of symmetry of the Fe8 molecule. The resonance frequency of the different lines are analyzed in terms of the hyperfine interactions.
