Mössbauer spectroscopy, Raman- and IR- microscopy studies of hysteretic behaviour in spincrossover systems

Abstract

The polymeric spin-crossover systems [Fe(atz)(X)2]2 (X =Cl-, CH3SO3-) have been investigated by complementary Mössbauer, and Raman and IR-microscopy as well as nuclear inelastic scattering (NIS). The systems reveal SCO transition temperatures around room temperature including hysteresis. Within the hysteresis loop the areas of LS and HS phases could be detected. © 2010 IOP Publishing Ltd.
