在本研究中，我们观察了锰（III）配合物[Mn-III(taa)] (H（3)taa =三（1-（2-偶氮基）-2-氮杂丁-4-基）胺）在强磁场下的光学吸收光谱。从零场的测量中，我们发现由于热诱导的自旋交叉跃迁，光谱在100 K和4.2 K之间发生了变化，这种变化发生在T (c)千分之一47 K左右。此外，在高场实验中，在T (c)以下观察到伴随场致自旋交叉的磁致变色现象。
In this study, we have observed the optical absorption spectra of the manganese(III) complex [Mn-III(taa)] (H(3)taa = tris(1-(2-azolyl)-2-azabuten-4-yl)amine), in high magnetic fields. From the measurements at zero field, we have found a variation of the spectrum between 100 K and 4.2 K due to the thermally-induced spin-crossover transition, which occurs around T (c) a parts per thousand 47 K. Furthermore, from the high-field experiment, a magnetochromism, accompanying with the field-induced spin-crossover, has been observed just below T (c) .
