Solution Synthesis of Halide Chiral Crystal with Controlled Dimension and Morphology

Recently, there has been a surge of research interest in understanding the intriguing spin-related phenomena in chiral materials. In this work, we present a solution-based approach for growing ferromagnetic chiral halide crystal. By tuning the temperature, growth time and concentration, we optimize the growth morphologies. We use X-ray diffraction and Raman spectroscopy to characterize the crystal structure and phase. The chirality is investigated by circular dichroism spectroscopy. The integration of ferromagnetism and chirality in the same crystal provides a rich platform for understanding spintronic phenomena.
