在具有感应磁织构的样品中研究了超细磁赤铁矿颗粒中 Fe3+ 离子磁矩的排列程度。纹理化样品是通过在磁场中冷冻含有 7.5 nm 磁赤铁矿颗粒的铁磁流体来制备的。对大磁场中纹理样品的穆斯堡尔光谱研究表明，缺乏完全对准并不是最近提出的大磁各向异性的影响，而是由于单个自旋的倾斜造成的。
The degree of alignment of the magnetic moments of Fe3+ ions in ultrafine maghemite particles has been studied in samples with induced magnetic texture. The textured samples were prepared by freezing ferrofluids, containing 7.5 nm maghemite particles, in a magnetic field. Mossbauer spectroscopy studies of the textured samples in large magnetic fields demonstrate that the lack of full alignment is not an effect of large magnetic anisotropy, as suggested recently, but that the effect is rather due to canting of individual spins.
