通过使用弱调制激光强度，我们成功地可逆地控制热滞内部自旋交叉（SC）单晶 [{Fe(NCSe)(py)2 }2 (m-bpypz)] 的动力学。该实验可以重复多次，高自旋-低自旋界面具有可重复的响应，并且不会损坏晶体。作为激励幅度和频率函数的深入研究揭示了截止频率大约的存在。 1.5赫兹。结果不仅证明了 SC 材料作为执行器、存储器件或开关的适用性，而且还为热滞内部自旋跃迁的可逆光控制开辟了一条新途径。
By using a weak modulated laser intensity we have succeeded in reversibly controlling the dynamics of the spin-crossover (SC) single crystal [{Fe(NCSe)(py)2 }2 (m-bpypz)] inside the thermal hysteresis. The experiment could be repeated several times with a reproducible response of the high-spin low-spin interface and without crystal damage. In-depth investigations as a function of the amplitude and frequency of the excitation brought to light the existence of a cut-off frequency ca. 1.5 Hz. The results not only document the applicability of SC materials as actuators, memory devices, or switches, but also open a new avenue for the reversible photo-control of the spin transition inside the thermal hysteresis.
