论文摘要
我们报告了一种优化的化学蒸气传输方法，该方法允许在质量上生长高达500毫克的FEP单晶，体积为80 $ mm^{3} $。通过这种方法获得的高质量通过EDX，高分辨率TEM，低温单晶XRD和中子衍射实验证实。我们研究了单晶的传输和磁性，并计算了FEP的电子带结构。我们在理论上还是在实验上都表明了FEP的基态是金属的。对磁数据的检查揭示了t $ _ {n} $ = 119 K以下的抗磁性顺序，而传递在顺磁性和抗磁磁相中的运输均保持金属。中子衍射数据的分析显示了与传播矢量q =（0，0，0，$ \pmδ$）的不相关磁性结构，其中$δ$ $ \ sim $ 0.2。为了充分了解磁态，需要进一步的实验。大型高质量单晶的成功生长为使用多种实验工具进一步研究了具有不超量自旋结构的巡回磁铁的机会。
We report an optimized chemical vapor transport method, which allows growing FeP single crystals up to 500 mg in mass and 80 $mm^{3}$ in volume. The high quality of the crystals obtained by this method was confirmed by means of EDX, high-resolution TEM, low-temperature single crystal XRD and neutron diffraction experiments. We investigated the transport and magnetic properties of the single crystals and calculated the electronic band structure of FeP. We show both theoretically and experimentally, that the ground state of FeP is metallic. The examination of the magnetic data reveals antiferromagnetic order below T$_{N}$ =119 K while transport remains metallic in both the paramagnetic and the antiferromagnetic phase. The analysis of the neutron diffraction data shows an incommensurate magnetic structure with the propagation vector Q=(0, 0, $\pmδ$), where $δ$ $\sim$ 0.2. For the full understanding of the magnetic state, further experiments are needed. The successful growth of large high-quality single crystals opens the opportunity for further investigations of itinerant magnets with incommensurate spin structures using a wide range of experimental tools.
