Poster: Single Crystal Growth and Characterization of NdFeO₃ : A Novel Candidate for Topological Magnons

Topological magnons have garnered substantial interest due to their potential in enabling low-dissipation and resilient magnonic devices, which hold promise for advancing energy-efficient information processing and spintronics. NdFeO₃, an orthorhombically distorted perovskite, stands out as a prominent candidate for realizing room-temperature topological magnons. With a Néel temperature of 760 K, NdFeO₃ hosts both Nd³⁺ and Fe³⁺ magnetic sublattices, fostering complex magnetic interactions. Theoretically, applying a magnetic field along the [001] direction can induce Weyl magnons by shifting the magnetic space group from Pn'ma' to P2₁/c', positioning this material as a promising platform for investigating topological magnon phenomena. We have successfully grown high-quality NdFeO₃ single crystals using the optical floating zone technique and will present comprehensive characterizations through Physical Property Measurement System (PPMS) and Superconducting Quantum Interference Device (SQUID) magnetometry to further explore and validate its magnetic and topological properties.
