| 中文摘要 | The nature of the charge ordering (CO) in Fe2BO4 was carefully examined by in situ TEM observations from 360 K down to 20 K. An incommensurate structural modulation with the wave vector q = (1/2, 0, epsilon) becomes plainly visible in association with the CO transition at T-CO approximate to 340 K. Careful structural analysis suggests that this incommensurate structure originates from a well-defined Fe2+/Fe3+ ionic order along the FeO6 octahedral ribbons (in the a-axis direction) and from a discommensurate antiphase stripe order along the c-axis direction. The average periodicity of antiphase stripes changes notably with lowering temperature and, via certain intermediate states, toward a superstructure phase with modulation wave vector of q = (1/2, 0, 0) at similar to 150 K in association with a magnetic phase transition. |
