“…47 In the YbFeO 3 compounds, the coupling between Yb 3+ and Fe 3+ is parallel. 45 Based on the above considerations, we assumed that the magnetic moment couplings of Yb 3+ and FM are also parallel. When the direction of the applied magnetic field is changed, Yb 3+ rotates under the influence of the external magnetic field, and the AFM coupling of Fe 3+ /Cr 3+ shows a pinning effect on it, hindering its rotation, and thus an EB phenomenon appears.…”

“…13 Recently, the net magnetic moment of PrFeO 3 in the lowtemperature region under very low field 5 Oe was reported to shift from the c-axis to the a-axis with increasing temperature, indicating a Γ 4 −Γ 2 SR transition in a PrFeO 3 single crystal. 9 In addition to PrFeO 3 , it is known for most RFeO 3 families; such SR transitions with Γ 4 states in the high-temperature region and Γ 2 states in the low-temperature region have been reported for ErFeO 3 , 14−17 YbFeO 3 , 18 SmFeO 3 , 8,10 etc. In the RFeO 3 family, SR transitions or the induced new magnetic phase transitions in RFeO 3 are often regulated through the rare-earth site or transition metal-site ionic doping.…”

“…In addition to SR transition, the spin switching effects have attracted further attention from many researchers, which is the phenomenon in which the magnetization of RFeO 3 flips or jumps under a specific magnetic field and temperature. The spin switching effect has been observed in SmFeO 3 , NdFeO 3 , DyFeO 3 , PrFeO 3 , YbFeO 3 , and ErFeO 3 . The magnetization vs temperature curves of ErFeO 3 show a “butterfly” shape, which is characterized by the parallel and/or antiparallel magnetic moment configurations between Er 3+ and Fe 3+ magnetic sublattices at a specific temperature during the magnetic measurements in the warming and cooling process, resulting in the type-I spin switching effect .…”

Field-tuning mechanisms of spin switching and spin reorientation (SR) transition were investigated in a series of highquality single crystal samples of Pr x Er 1−x FeO 3 (x = 0, 0.1, 0.3, 0.5) prepared using the optical floating zone method. The single crystal quality, structure, and axis orientation were determined by roomtemperature powder X-ray diffraction, back-reflection Laue X-ray diffraction, and Raman scattering at room temperature. Magnetic measurements indicate that the type and temperature region of SR transition are tuned by introducing different ratios of Pr 3+ doping (x = 0, 0.1, 0.3, 0.5). The trigger temperatures of spin switching and magnetization compensation temperature of Pr x Er 1−x FeO 3 crystals can be adjusted by doping with different proportions of Pr 3+ . Furthermore, the trigger temperature of the two types of spin switching in Pr 0.3 Er 0.7 FeO 3 along the a-axis can be regulated by an external field. Meanwhile, the isothermal magnetic field-triggered spin switching effect is also observed along the a and c-axes of Pr 0.3 Er 0.7 FeO 3 . An in-depth understanding of the magnetic coupling and competition between the R 3+ and Fe 3+ magnetic sublattices, within the RFeO 3 system, has important implications for advancing the practical applications of the relevant spin switching materials.

“…Rare earth orthoferrites, denoted as RFeO 3 (R = rare earth), have attracted significant attention due to their exceptional physical properties. These compounds exhibit a range of intriguing phenomena, such as spin reorientation (SRT), spin switching (SSW), magnetic compensation, multiferroicity, exchange bias, optically controlled ultra-fast dynamics, long-range spin transport, and magnetocaloric effects [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. They possess an orthorhombically distorted perovskite crystal structure with the Pbnm space group.…”

We investigated spin reorientation, magnetic compensation and spin switching transitions in a series of high-quality single crystals of Er1-xSmxFeO3 (x = 0, 0.2, 0.4, 0.6, 0.8) prepared using the optical floating zone method. Structural and other preliminary characterizations confirmed the quality and phase purity of the crystals. Rietveld refinement of powder XRD data indicates that lattice parameters a and c increase linearly with increasing Sm concentration, whereas b remained constant. Field-cooled cooling (FCC) measurements revealed a temperature-induced spin reorientation transition (SRT) from Γ4 (Gx, Ay, Fz) to Γ2 (Fx, Cy, Gz) for all the samples. SRT temperature increased with Sm concentration and spread widely above and below room temperature. Moreover, magnetic compensation is common to all the compositions but decreases as Sm doping increases. We also observe type-I spin switching in samples with x= 0, 0.2, and 0.4 at an applied field of 60 Oe under FCC protocol, with a reduction in spin switching temperature as Sm content increased. For Sm-rich samples (x= 0.6, 0.8), spin switching was absent at 60 Oe.
