Mainz University Manganese Spintronics Breakthrough

Researchers at University of Mainz have developed a novel manganese-based molecular material that allows for data storage at significantly higher temperatures than previous iron-based materials. This breakthrough in spintronics raises the operating temperature for potential storage devices to around minus 132 degrees Celsius, outperforming the previous maximum of 130 Kelvin (minus 143 degrees Celsius) for iron-containing materials. The new material, synthesized by Sandra Kronenberger under the leadership of Prof. Dr. Katja Heinze, utilizes manganese combined with carbene ligands to stabilize spin states, which serve as information storage. The research, with magnetic behavior measured by Dr. Luca Carrella, was published in Nature Chemistry, and is expected to pave the way for future digital storage technologies by reducing the energy requirements for cooling memory devices.
