Meltable Spin Transition Molecular Materials with Tunable Tc and Hysteresis Loop Width

Abstract

Herein, we report a way to achieve abrupt high-spin to low-spin transition with controllable transition temperature and hysteresis width, relying not on solid-state cooperative interactions, but utilizing coherency between phase and spin transitions in neutral Fe(II) meltable complexes.

Keywords: magnetism; phase transitions; soft matter; spin transitions; thermochromism.
