Micrometer-sized defects, induced by laser ablation, radically change the spatiotemporal dynamics of a first-order structural phase transition, in this case of a spin crossover material. This type of "domain engineering" is thus based on artificial defects, such as that in the image, which can serve either as nucleation sites or as pinning sites. The subsequent growth of the nucleated domains can also be guided to some extent.
微米级缺陷，由激光烧蚀诱导，从根本上改变了一级结构相变的时空动力学，在这种情况下是自旋交叉材料。这种类型的“畴工程”是基于人工缺陷，如图像中的缺陷，它可以作为成核位点或钉扎位点。随后，成核畴的生长也可以在一定程度上得到引导。
