Iron(III) Spin Crossover Compounds [PDF]

, 2004
In this chapter, selected results obtained so far on Fe(III) spin crossover compounds are summarized and discussed. Fe(III) spin transition materials of ligands containing chalcogen donor atoms are considered with emphasis on those of N,N-disubstituted-dithiocarbamates, N,N-disubstituted-XY-carbamates (XY=SO, SSe, SeSe), X-xanthates (X=O, S), monothio ...

Modeling Problems of Spin Crossover Nanocrystals

, 2017
The most important approaches which describe the behavior of spin crossover compounds have been reviewed. Thermodynamic consideration of spin crossover phenomenon is one of the most general able to describe theoretically almost any kind of transition in spin crossover system.
