| contents | We investigate the magnetic behavior of polycrystalline CeCr$_x$Fe$_{1-x}$O$_3$ (x = 0, 0.33, 0.67, and 1) synthesized via solid state reaction. Rare earth orthoferrite and orthochromite materials are well known for exhibiting spin reorientation transitions. Cr$^{3+}$ doping in CeFeO$_3$ results in the unusual occurrence of two spin reorientation transitions, $Γ_4$(G$_x$, A$_y$, F$_z$) $\rightarrow$ $Γ_1$(A$_x$, G$_y$, C$_z$) near 230 K and $Γ_4$(G$_x$, A$_y$, F$_z$) $\rightarrow$ $Γ_2$(F$_x$, C$_y$, G$_z$) near 100 K. In addition, two Néel transitions are identified. The results indicate that CeCr$_x$Fe$_{1-x}$O$_3$ offers a rich collection of magnetic behaviors with application potential for spintronic devices. |
