TL;DR: In this article, structural fatigability of spin crossover materials with regard to structural fatigue was measured by measuring single-crystal mosaicity, and it was shown that fatigability can affect non-cooperative SCO systems.

TL;DR: In this article, the complex optical index refraction of an iron (II) spin-crossover coordination polymer is measured in the Terahertz frequency range by TeraHERtz time-domain spectroscopy (THz-TDS).

TL;DR: In this paper, the interaction of a CO2 laser with a host matrix, in which spin-crossover compounds are diluted, makes it possible to induce a low-spin-to-high-spin transition.

TL;DR: The thermal and light-induced magnetic properties of a family of discrete magnetically switchable 'nanoball' species (3 nm in diameter) are reported in this article, where the self-assembly of these materials is accomplished by the use of the metallo building block, [Cu([Tp{sup 4-py])(NCCH{sub 3})] ([Tp {sup 4py}]=tris-[3-(4{prime}-pyridyl)pyrazol-1-yl]hydroborate], combined with a [Fe

TL;DR: H2O (with bpp=2,6-bis(pyrazol-3-yl)-pyridine and ox=oxalate) was prepared, and its spin crossover behavior was characterized, showing a strong dependence on the heating and cooling rate.
