本文对（Co0.9757Fe0.03）4 Nb 2 O 9化合物进行了详细的~（57）Fe穆斯堡尔谱学研究，以探讨其可能的磁性结构。我们已经表明，以前报道的磁结构不能令人满意地描述我们的低温穆斯堡尔谱。因此，结合理论计算，我们提出了一个调制螺旋磁结构，可以用来模拟我们的整个系列的低温穆斯堡尔谱。我们的研究结果表明，以前报道的不同的磁结构的组合只是近似的平均磁结构从我们的调制螺旋模型。我们预计，提出的调制非共线磁结构可能会揭示在这个系统中观察到的复杂磁电效应的理解。
In this work, we present detailed57Fe Mössbauer spectroscopy investigations of (Co0.9757Fe0.03)4Nb2O9compound to study its possible magnetic structure. We have shown that the previously reported magnetic structures cannot satisfactorily describe our low temperature Mössbauer spectra. Therefore, in combination with theoretical calculations, we have proposed a modulated helicoidal magnetic structure that can be used to simulate the whole series of our low temperature Mössbauer spectra. Our results suggest that the combination of previously reported different magnetic structures are only approximations of the average magnetic structure from our modulated helicoidal model. We anticipate that the proposed modulated non-collinear magnetic structure might shed light on the understanding of the complex magnetoelectric effects observed in this system.
