Abstract: We systematically investigated the magnetic properties of a single crystal bulk Fe3O4 at low temperatures. Below Verwey transition, the magnetization versus temperature curves under zero-field cooling present anomalous behaviors for [1 0 0], [1 0 1] and [0 0 1] directions, respectively. Furthermore, at Verwey temperature, a high sensitivity of relative magnetization change (Delta M/M) to small magnetic field and, in particular, a reversal of Delta M/M at moderate magnetic field range for [0 0 1] direction is observed. Our work demonstrates a very important role of magnetic axis reorientation effect in low temperature magnetic properties of magnetite, which will stimulate further research on the intricate microscopic physics mechanisms in this classic material.
