Spin Transition Molecular Materials: New Sensors

摘要

This short review article concerns a new family of iron(Ⅱ) spin transition chain compounds containing 4-R-l,2,4-triazole derivatives whose properties have been followed by several physical techniques. A clear evidence of the LIESST effect at 20 K has been found for one of these materials by ~(57)Fe Moessbauer spectroscopy. Potential applications in terms of pressure and thermal sensors are discussed.
