Creation of Highly Magnetic Material Could Improve Computer Technologies
March 15, 2017 | University of BristolEstimated reading time: 1 minute
Scientists, led by Professor Ian Manners from the University of Bristol's School of Chemistry, have developed a facile route to a highly magnetic material that could provide fundamental improvements to the performance of current computer technologies.
Polymers, or plastics, which feature metal atoms in their structure have been a focus of much research in recent decades, and have found application in self-healing materials, photovoltaic technology, and information storage.
Metal sandwich complexes, commonly termed 'metallocenes' have also been incorporated into polymeric materials – most commonly using iron.
Now, researchers from the University of Bristol, together with colleagues from the University of Oxford have created a polymer in which nickel (as ‘nickelocene’ units) is built into the structure, affording a bright green, highly magnetic material.
The study's first author Rebecca Musgrave said: "Remarkably, we also have the ability to create and destroy this dynamic magnetic polymer using only changes in temperature (via a process called depolymerisation).
"Most materials with cooperative magnetic properties are insoluble or difficult to process, and this nickel-based polymer is a rare example of a readily accessible, easily handled, soluble magnetic polymer."
The interesting electronic and magnetic properties of this polymer will continue to be explored, with the aim of making highly magnetic materials for use in data storage applications, key to improving the performance of current computer technologies.

The Need for a Holistic Global Sustainability Standard
04/10/2024 | Michael Ford, Aegis SoftwareNo one can deny that the resources of our fragile planet are finite. The environment seems like a third party, subject to constant degradation. We’re acutely aware of the effects of pollution on our climate, and despite our “throw-away” culture, recycling and recovery of materials has remained relatively expensive, even as we use more energy just to survive.
