本章回顾了最近的自旋交叉（SCO）材料的压电和光晶体学方法，强调了结构特征在SCO过程中的作用。上海合作组织现象具有高度的压力敏感性。本章强调了高压下的晶体学，即压电晶体学在上合组织领域的必要性。这说明光晶体学实验不仅仅是激光照射下的数据收集。结果表明，通过改变不同的外部参数（如温度、激光照射波长或功率）和仔细研究结构特征，可以获得不同工艺的关键信息。例如，已经观察到，对于某些系统，通过选择适当的激发波长可以触发光诱导态的性质。
This chapter reviews recent piezo‐ and photo‐crystallographic approaches to spin‐crossover (SCO) materials highlighting the role of structural features in the SCO process. The SCO phenomenon is highly pressure‐sensitive. The chapter emphasizes the need for crystallography under high pressure, that is piezo‐crystallography, in the field of SCO. It illustrates that photo‐crystallography experiments are not merely data collections under laser irradiation. Accordingly, it is shown that through varying different external parameters (such as temperature, laser irradiation wavelength or power) and careful investigation of the structural signatures, key information on the different processes can be obtained. For instance, it has been observed that for some systems the nature of photoinduced state can be triggered by choosing appropriate excitation wavelength.
