Negative zero‐field‐cooled magnetization and magnetic switching in multiferroic Lu0.5Sc0.5FeO3 ceramics

“…28 While the LSFO samples show negative magnetization only in the ZFC mode. For the latter mechanism, the negative magnetization is contributed from the inequivalent magnetic sublattices as observed in ErFe 0.55 Mn 0.45 O 3 32 and Ni(Cr 1-x Mn x ) 2 O 4 . 34 Theoretically, there is only one magnetic sublattice about Fe 3+ ion in LSFO with nonmagnetic cation of Lu 3+ and Sc 3+ ions.…”

“…26 In recent years, researchers have found that perovskite RMO 3 (R: rare-earth element, M: transition-metal element) oxides are good material systems for studying negative magnetization. [27][28][29][30][31][32][33][34] For R within nonmagnetic state in perovskite RMO 3 oxides with only one magnetic sublattice, such as YVO 3 , 28 YFe 0.5 Cr 0.5 O 3 , 30 and BiFe 0.5 Mn 0.5 O 3 , 31 the origin of the negative magnetization may be from the competition of magnetocrystalline anisotropy and the Dzyaloshinsky-Moriya (D-M) interaction or other possible explanations.…”

“…For R within magnetic state in perovskite RMO 3 oxides with two magnetic sublattices, such as YbCrO 3 , 29 ErFe 0.55 Mn 0.45 O 3 , 32 and LuCr 1-x Mn x O 3 , 33 the negative magnetization is attributed to the antiferromagnetic coupling between the transition-metal and rare-earth moments. As such an important magnetic phenomenon, relevant review articles have systematically described the mechanism of negative magnetization.…”

Spin-Reorientation Transition Driven by Double Exchange in CeFeO3 Ceramics

“…13 is the most peculiar and interesting phenomenon of RFeO 3 . 14 Specifically, there are three kinds of spin configurations for the Fe 3+ magnetic sublattices in RFeO 3 (Γ 1 (Ax, Gy, Cz), Γ 2 (Fx, Cy, Gz), and Γ 4 (Gx, Ay, Fz)). 1 When the temperature drops to the Neel temperature, the spin configuration of Fe 3+ ions begins to present in a G-type antiferromagnetic (AFM) arrangement along the a-axis with weak ferromagnetic (FM) vector along the c-axis, i.e., Γ 4 (Gx, Ay, Fz) state.…”

“…There are three kinds of magnetic interactions: Fe 3+ –Fe 3+ , R 3+ –Fe 3+ , and R 3+ –R 3+ in the material, each of which is composed of isotropic, anisotropic antisymmetric, and symmetric exchange interactions, making the RFeO 3 unique and novel in magnetism such as SR, zero magnetization, and spin flip. − The SR transition referring to the process in which easy axis of the magnetization changes from one crystallographic axis to another one under the external field (magnetic field, temperature, pressure, laser pulse, etc. ) is the most peculiar and interesting phenomenon of RFeO 3 . Specifically, there are three kinds of spin configurations for the Fe 3+ magnetic sublattices in RFeO 3 (Γ 1 (A x , G y , C z ), Γ 2 (F x , C y , G z ), and Γ 4 (G x , A y , F z )) .…”
