Electronic phase separation into charge-ordered (CO) and charge-averaged (CA) phases in $\mathrm{Ca}{\mathrm{Fe}}_{3-x}{M}_x{\mathrm{O}}_5$ samples for dopants $M=\mathrm{Mn}$ and Co has been investigated using powder neutron and x-ray diffraction, magnetization, and Mössbauer spectroscopy measurements. Electronic phase separation is observed in lightly doped $\mathrm{Ca}{\mathrm{Fe}}_3{\mathrm{O}}_5$ samples, where $4–10\%$ Ca is replaced by Mn, Fe, or Co, and the CA ground state is stabilized at higher doping levels. The CO and CA phases are found to emerge below a common magnetic ordering temperature at $300–320\mathrm{K}$ providing strong evidence for a lattice strain-driven mechanism that couples their magnetic transitions.

CaFe3O5中电子相分离的替代调节

电子相分离为电荷相（CO）和电荷平均（CA）相 $钙{铁}_{3-X}{\mathrm{中号}}_X{\mathrm{Ø}}_5$ 掺杂剂样品 $\mathrm{中号}=锰$已经使用粉末中子和X射线衍射，磁化强度和Mössbauer光谱测量法对Co和Co进行了研究。在轻掺杂中观察到电子相分离$钙{铁}_3{\mathrm{Ø}}_5$ 样品在哪里 $4–10％$Ca被Mn，Fe或Co代替，并且CA基态在较高的掺杂水平下稳定。发现CO和CA相出现在共同的磁有序温度以下$300–320\mathrm{ķ}$ 为结合其磁跃迁的晶格应变驱动机制提供了有力证据。
