用X射线衍射法在室温下研究了BaMgFe6O11Y型六方铁氧体单晶。镁离子阳离子的量/FU。是0.70(1)而不是1，从而导致Fe2+的存在。除了T-块的(6cIV)八面体位置外，这些镁离子分布在结构的所有位置，并明显优先于T-S块体边界的(18hVI)八面体位置(∼58%)。
By means of X-ray diffraction, a single crystal of BaMgFe6O11Y-type hexagonal ferrite has been studied at room-temperature. The amount of Mg2+cation/f.u. is 0.70(1) instead of 1 leading to the presence of Fe2+. These Mg2+cations are located in all the sites of the structure except in the (6cIV) octahedral site of the T-block, with a marked preference (∼58%) for the (18hVI) octahedral site at the T-S blocks boundary.
