This invention provides a Cr2Se3 single crystal and its preparation method, relating to the field of crystal materials technology. The Cr2Se3 single crystal preparation method, from raw material proportioning and powder preparation to single crystal growth, involves coordinated steps to suppress impurity introduction and impurity phase formation, while simultaneously promoting ordered atomic arrangement and eliminating lattice vacancies and dislocations, resulting in a Cr2Se3 single crystal with good single-phase properties, high crystallinity, and extremely low defect density. The high-purity, low-defect single crystal structure ensures its semiconductor transport properties and antiferromagnetic order; it also eliminates interference from impurity scattering and lattice distortion, optimizing the magnetic field's control over the magnetic moments of Cr atoms, enabling the single crystal to exhibit a strong CMR effect approaching -100%. Furthermore, the coordinated steps ensure consistency in size, phase composition, and structural integrity of the prepared Cr2Se3 single crystal, significantly improving the success rate, process controllability, and repeatability.
