N2 - Temperature dependence of 57Fe NMR was measured above the Verwey transition in three Fe3-xAlxO4 (x=0, 0.005, 0.03) single crystals. The satellite lines corresponding to Fe (A) which have a single Al (B) nearest neighbor were detected in the NMR spectra of x=0.005 and 0.03 compounds. Temperature dependence of NMR linewidth for x=0.03 indicates that the electron density becomes inhomogeneous as T¿TV.
