The results of AC magnetic susceptibility measurements of zinc ferrite (Fe3-xZnxO4, x = 0, 0.0072, 0.0174, 0.049) single crystalline samples under pressure up to 1.2 GPa in the temperature range close to the Verwey transition temperature (T-v) are reported. The isotropy point Tip increases with pressure for each x but the disappearance of primary anisotropy constant at T-IP has no effect on Mossbauer spectrum at ambient pressure. Finally, Mossbauer effect data in the vicinity of the Verwey transition does not support the recent claim of the inverse to normal spinel crossover at the transition.
