“…YFeO 3 crystallizes in the D 2 h 16 Pnma space group with a distorted perovskite structure, which is a canted antiferromagnet ( T N ≈ 650 K) because the atomic moments align at an angle to the c -axis. The weak ferromagnetism in YFeO 3 is mainly caused by anisotropic superexchange . Anisotropic magnetic behavior has been reported in the floating zone method grown YFeO 3 single crystal, in which magnetization normal to the (100) direction shows the largest coercive field and parallel to (100) the biggest saturation magnetization .…”

Controllable growth of perovskite oxide with tailored shapes is challenging but promising for shape-dependent physical and chemical property studies and probable applications. In this article, we report a general method for tailoring the crystal shape of perovskite structure rare-earth ferrite (REFeO3) crystals in hydrothermal conditions. By adjusting the ratio of KOH to urea, various shapes of REFeO3 crystals can be prepared, such as LaFeO3 truncated cubes, PrFeO3 perpendicular cross prisms, SmFeO3 crossed bars with trustum, DyFeO3 double pyramids on cubes, ErFeO3 distorted octahedrons, and YFeO3 long bars and thick hexagonal elongated plates. Detailed shape tailoring conditions for each phase of the crystals have been discussed clearly. The structure-dependent shape growing mechanism for each REFeO3 is generally discussed by consideration of the variance of reduced unit cell parameters in reference to the ideal cubic ABO3 perovskite structure. DyFeO3 was taken as an example to elucidate the crystal shape formation mechanism based on the Bravais–Friedel–Donnay–Harker theory. The magnetic property of the YFeO3 crystal shows shape dependence: elongated bars have the highest saturated magnetization, while the lowest coercive field, while the tailored polyhedrons are vice versa. This paper not only builds a general technique for tailoring the crystal shape to various shapes of REFeO3 crystals but also provides many crystals for further study and application of anisotropy either in physical or in chemical properties.

“…The striking feature of orthoferrites is their high Néel temperature T N , which for YFeO 3 is reported [6][7][8] to be approximately 644 K. This property could, in principle, result in room-temperature applications. Below T N , the iron spins S = 5/2 order in an antiferromagnetic (AFM) state 4 (G a , F c , A b ), where the spins are canted, resulting in a weak ferromagnetic (FM) component along the c axis [9,10].…”

We measured absorption of THz radiation in YFeO 3 single crystals at a temperature of 3 K in the magnetic field up to 17 T applied in all three crystallographic directions. Two spin-wave modes were observed at the point with energies 1.2 meV (9.8 cm −1) and 2.4 meV (19.3 cm −1) in zero field. From the magnetic-field dependence of mode energies, we have refined the previously proposed model [S. E. Hahn et al., Phys. Rev. B 89, 014420 (2014)] and quantified the parameters of Dzyaloshinskii-Moriya interactions and single-ion anisotropies.

In antiferromagnets, the efficient transport of spin-waves has until now only been observed in the insulating antiferromagnet hematite, where circularly (or a superposition of pairs of linearly) polarized spin-waves diffuse over long distances. Here, we report long-distance spin-transport in the antiferromagnetic orthoferrite YFeO3, where a different transport mechanism is enabled by the combined presence of the Dzyaloshinskii-Moriya interaction and externally applied fields. The magnon decay length is shown to exceed hundreds of nanometers, in line with resonance measurements that highlight the low magnetic damping. We observe a strong anisotropy in the magnon decay lengths that we can attribute to the role of the magnon group velocity in the transport of spin-waves in antiferromagnets. This unique mode of transport identified in YFeO3 opens up the possibility of a large and technologically relevant class of materials, i.e., canted antiferromagnets, for long-distance spin transport.
