本文研究了Er_（1-x）Y_xFeO_3（x= 0，0.25，0.5，0.75，1）系列单晶中由温度引起的自旋重取向转变。通过掺杂Y3+，我们将自旋重取向温度随x的增加而调向低温。此外，ErFeO 3的典型补偿点和自旋翻转跃迁也随着掺杂量的增加而降低，当x = 0：75时消失.我们还报道了Er_（1-x）Y_xFeO_3的Rietveld精细化和拉曼光谱，其中一些拉曼峰随着掺杂的增加而向低频移动。我们的研究结果有助于理解稀土（R3+）和铁（Fe 3+）两种磁性亚晶格之间的相互作用，也有助于材料的设计和潜在的应用。
A temperature-induced spin reorientation transition between Γ4(Gx,Ay,Fz) and Γ2(Fx,Cy,Gz) has been studied in the family of Er1-xYxFeO3(x= 0, 0.25, 0.5, 0.75, 1) single crystals. By doping nonmagnetic Y3+, we tuned the spin reorientation temperature to low temperature with increasingx. Moreover, the typical compensation point and spin flip transition of ErFeO3also decreases with doping, and disappears abovex= 0:75. We also report the Rietveld refinements and Raman spectroscopy of Er1-xYxFeO3, where some Raman peaks are shifted to low frequency with increasing doping. Our results shed light on the understanding of the interaction between two magnetic sub-lattices of rare earth (R3+) and iron (Fe3+) ions, and will also contribute to the materials design and potential applications.
