Mainz University succeeds in the first round of the new Carl Zeiss Foundation Wildcard program / Researchers present an innovative approach for enhancing electronic devices. Two chiral molecules on chiral spin structures in a magnetic thin film - 26 October 2022 Researchers at Johannes Gutenberg University Mainz (JGU) are pursuing a completely new and unconventional strategy to improve the way data can be processed and - in particular - stored. Together with their partners at the Hebrew University of Jerusalem, they have been granted funding by the Carl Zeiss Foundation (CZS). The team members, based in Mainz and Jerusalem, have come up with the idea of bringing together two different forms of chirality to develop new data storage systems that are faster, smaller, and more efficient than those currently available. Chirality, also known as handedness in this context, describes objects that come in two distinctly different configurations that are mirror images of each other such as our left and right hand. "We were inspired by nature, where chirality is a common phenomenon. Chiral molecules can act like a filter for electron spin and ensure functionality even on the smallest scale," said Professor Angela Wittmann of the JGU Institute of Physics, the spokesperson of the new HYMMS - Hybrid chiral Molecule-Magnetic Systems research project.
