Summary of the previously reported magnetic structures of RE³⁺ and Cr³⁺ ions in RECrO₃ (RE = Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu) compounds

RECrO3	RE3+	Cr3+	SR	Cr3+

GdCrO3	FxCy	FxGz	√	GxFz
TbCrO3	FxCy	–	–	FxGz
DyCrO3	GxAy	–	–	FxGz
HoCrO3	−Fx−Cy	–	–	Gz
ErCrO3	−Cz	Gy	√	GxFz

The crystal structure is orthorhombic with the Pbnm space group (No. 62). Here $T_{\text{N}}^{\text{RE}}=\text{AFM}$ transition temperature of RE³⁺ ions; SR = spin reorientation; $T_{\text{SR}}^{\text{Cr}}=\text{SR}$ temperature of Cr³⁺ ions; $T_{\text{N}}^{\text{Cr}}=\text{AFM}$ transitions temperature of Cr³⁺ ions. The check mark (√) represents that there exists a magnetic SR phase transition. These were summarized from the following references: GdCrO₃ (Cooke et al., 1974), TbCrO₃ (Gordon et al., 1976), DyCrO₃ (Bertaut, 1963; Krynetskii and Matveev, 1997; Tamaki et al., 1975), HoCrO₃ (Shamir et al., 1981; Su et al., 2011), ErCrO₃ (Hornreich, 1978; Shamir et al., 1981), TmCrO₃ (Shamir et al., 1981), YbCrO₃ (Shamir et al., 1981), and LuCrO₃ (Shamir et al., 1981).
