Tuning spin reorientation in Er1- x Y x FeO3 single crystal family

A temperature-induced spin reorientation transition between Γ₄ (G_x, A_y, F_z) and Γ₂ (F_x, C_y, G_z) has been studied in the family of Er_1-xY_xFeO₃ (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 Er_1-xY_xFeO₃, 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.
