Abstract

Molecular toolkit is a crucial part of futuristic spintronics and quantum information technologies. Magnetic bistability is the basis for such applications, which can be achieved by spin crossover (SCO) systems and single molecular magnets (SMMs). The SCO phenomenon relies on cooperativity, while the latter defies it. For the first time, a recent report by Galán-Mascarós and coworkers outlined the occurrence of memory effect in a trinuclear iron spin crossover system through its incorporation in a solid-state diamagnetic matrix or as a dilute solution. The fact that this molecule can show a memory effect on dilution, almost at a molecular level, opens up new possibilities for SCO systems doubling up as single-molecule magnets at elevated temperatures in the foreseeable future.

Graphical abstract

Memory effect in a trinuclear iron spin crossover system by incorporating it in a solid-state diamagnetic matrix or as a dilute solution opens up new vistas in molecular magnetism is detailed in this article.

未来的存储设备:稀土的单分子磁体与地球上丰富金属的自旋交叉系统
分子工具箱是未来自旋电子学和量子信息技术的重要组成部分。磁双稳定性是这种应用的基础,它可以通过自旋交叉(SCO)系统和单分子磁体(smm)来实现。上海合作组织现象依赖于合作,而合作则反对合作。最近,Galán-Mascarós及其同事的一份报告首次概述了在三核铁自旋交叉系统中通过将其掺入固态抗磁基质或作为稀释溶液来发生记忆效应。事实上,这种分子几乎在分子水平上可以显示出对稀释的记忆效应,这为SCO系统在可预见的未来在高温下加倍作为单分子磁体开辟了新的可能性。摘要本文详细介绍了将三核铁自旋交叉体系中的记忆效应与固态抗磁基体结合或作为稀释溶液,为分子磁学研究开辟了新的前景。

期刊介绍: Journal of Chemical Sciences is a monthly journal published by the Indian Academy of Sciences. It formed part of the original Proceedings of the Indian Academy of Sciences – Part A, started by the Nobel Laureate Prof C V Raman in 1934, that was split in 1978 into three separate journals. It was renamed as Journal of Chemical Sciences in 2004. The journal publishes original research articles and rapid communications, covering all areas of chemical sciences. A significant feature of the journal is its special issues, brought out from time to time, devoted to conference symposia/proceedings in frontier areas of the subject, held not only in India but also in other countries.
