Abstract Phase behaviors and magnetic properties of magnetic ionic liquids (mILs) were investigated at low temperature. The mILs were [C4mim][FeCl4], [C4mim][FeCl3Br], [C4mim][FeCl2Br2], [C4mim][FeClBr3], and [C4mim] [FeBr4], where [C4mim]+ is 1-butyl-3-methylimidazolium.… Click to show full abstract
Abstract Phase behaviors and magnetic properties of magnetic ionic liquids (mILs) were investigated at low temperature. The mILs were [C4mim][FeCl4], [C4mim][FeCl3Br], [C4mim][FeCl2Br2], [C4mim][FeClBr3], and [C4mim] [FeBr4], where [C4mim]+ is 1-butyl-3-methylimidazolium. The formation of symmetric and asymmetric anions was identified using Raman spectroscopy. In addition, [C4mim][FeCl4], [C4mim][FeCl3Br], and [C4mim][FeCl2Br2] indicated a paramagnetic behavior of magnetic susceptibility, which obeyed the Curie-Weiss law. In [FeClBr3]−-, and [FeBr4]−-based mILs, crystallization was induced at a low temperature upon cooling. Moreover, nonparamagnetic magnetic susceptibility was observed in [C4mim][FeClBr3], and [C4mim][FeBr4].
