Graphene oxide (GO)-the oxidized form of graphene-is actively studied in various fields, such as energy, electronic devices, separation of water, materials engineering, and medical technologies, owing to its fascinating physicochemical properties. One major drawback of GO is its instability, which leads to the difficulties in product management. A physicochemical understanding of the ever-changing nature of GO can remove the barrier for its growing applications.

- The study focuses on growing high-quality single-crystal samples of hexagonal ferrite Ba(Fe Sc )O to better understand its helimagnetic structure and potential applications.
- Utilizing a spontaneous crystallization method with NaO-FeO flux, the researchers determined an optimal composition for growing the crystals, which resulted in lamellate structures measuring 13 mm × 8 mm × 2 mm.
- Analysis confirmed the crystals were of single-phase and high crystalline quality, with magnetic properties indicating helimagnetism, supported by temperature-dependent magnetization and neutron diffraction measurements.
