In a remarkable scientific achievement, researchers have devised a novel approach to enhance the production of single-molecule magnets (SMMs) by introducing a two-coordinate lanthanide complex. This breakthrough harbors significant potential for applications in high-density data storage, quantum computing, and the development of compact memory devices.
A team of scientists hailing from the esteemed University of Ottawa has pioneered an ingenious method to elevate the quality of molecule-based magnets, commonly referred to as single-molecule magnets (SMMs).
The scientists from the University of Ottawa have devised an unprecedented technique for enhancing molecule-based magnets, specifically single-molecule magnets (SMMs). This remarkable feat of synthetic prowess has yielded a two-coordinate lanthanide complex characterized by intrinsic magnetic properties inherent to the molecule itself. This advancement heralds the prospect of high-capacity hard drives, potential utilization in the realm of quantum computing, and the creation of swifter, more diminutive memory devices.
“This discovery serves as a blueprint for the creation of novel molecule-based materials for molecular electronics,” asserts Muralee Murugesu, a distinguished full professor within uOttawa’s Faculty of Science.
Lanthanide ions typically prefer to surround themselves with numerous organic ligands to stabilize and occupy their coordination sphere. However, through an innovative ligand design and synthetic methodology, the scientists at uOttawa have achieved the remarkable feat of isolating the rare and valuable two-coordinate species. Furthermore, they have unveiled a substantial energy level separation, a phenomenon hitherto only theorized. This synthetic achievement underscores the immense potential embodied within these molecules.
The research, conducted within the Department of Chemistry and Biomolecular Sciences at the University of Ottawa, was spearheaded by Muralee Murugesu, collaborating with Professor Akseli Mansikkamäki from the University of Oulu, Finland. The dedicated team also included uOttawa post-doctoral fellows Diogo A. Gálico and Alexandros A. Kitos, along with doctoral students Dylan Errulat and Katie L. M. Harriman.
“We have achieved highly promising results that not only validate theoretical predictions but also offer a synthetic pathway to improve molecular magnets. These magnets hold great promise in the creation of more compact and swifter memory devices and quantum computers, owing to their nanoscale dimensions and distinctive quantum attributes, such as quantum tunneling of magnetization and quantum coherence,” elucidates Professor Murugesu.
The Impactful Discovery
“We employed our CFI-funded equipment to scrutinize the magnetic and luminescent characteristics of our complexes at extremely low temperatures, below 10 Kelvin. These measurements unveiled the intricate electronic structure of our complexes. Additionally, we corroborated our findings through collaborative computational studies with Professor Mansikkamäki at the University of Oulu, Finland,” Professor Murugesu further highlights.
Since 2007, the Murugesu Group at the University of Ottawa has been dedicated to the exploration of single-molecule magnets (SMMs), capable of storing and processing information at the molecular level. This eagerly anticipated material holds the promise of conserving energy and space, ultimately leading to faster and superior electronics, potentially revolutionizing data storage and ushering in a new era of molecular electronics.
