Crystal Growth and Characterization of S=5/2 Triangular Chain Compound Bi₃FeMo₂O₁₂

Exploring the exotic magnetic properties of low-dimensional quantum magnets with geometrical frustration has become a captivating subject in condensed matter physics. Quantum fluctuations in these systems frequently lead to unconventional magnetic behaviors. Among them, one-dimensional systems are especially ideal for studying such phenomena, providing a unique platform to investigate exotic ground states. In our research, we successfully synthesized a pure polycrystalline sample of the quasi-one-dimensional system Bi₃FeMo₂O₁₂, characterized by S = 5/2 and comprising well-separated zig-zag iron (Fe) chains. Additionally, by employing a modified top-seeded solution growth (TSSG) technique, we have grown centimeter-sized single crystals of Bi₃FeMo₂O₁₂ using a vertical Bridgman furnace. Our magnetic and thermodynamic measurements reveal intriguing magnetic phase transitions that evolve under applied magnetic fields. In this presentation, I will discuss our latest experimental results, including insights from neutron powder diffraction studies.
