Observation of Dual Spin Reorientation Transitions in Polycrystalline CeCr$_x$Fe$_{1-x}$O$_3$(x=0.33 and 0.67)

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 $_{z}$ ) $\to$ $Γ_{1}$ (A $_{x}$ , G $_{y}$ , C $_{z}$ ) near 230 K and $Γ_{4}$ (G $_{x}$ , A $_{y}$ , F $_{z}$ ) $\to$ $Γ_{2}$ (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.
