A temperature-induced spin reorientation transition between Г4 (Gx, Ay, Fz) and Г2 (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 increasing x. Moreover, the typical compensation point and spin flip transition of ErFeO3 also decreases with doping, and disappears above x = 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.
