Researchers at The University of Manchester and the Australian National University have developed a new class of molecular magnets that combines the most successful features of\u00a0previous\u00a0designs, resulting in some of the strongest magnetic memory properties reported to date.\u00a0<\/p>\n

The work, published in\u00a0Nature Communications,<\/a>\u00a0centres on single-molecule magnets (SMMs), a class of materials capable of storing magnetic information within individual molecules.\u00a0These\u00a0materials are being explored as candidates for future ultra-high-density data storage technologies,\u00a0as they offer the potential for information to be stored\u00a0on a dramatically smaller scale than in conventional magnetic devices.\u00a0<\/p>\n

Controlling the geometry of lanthanide compounds has long been one of the major challenges in molecular magnet design. The researchers have overcome part of that challenge by combining two molecular architectures that had previously delivered strong, but different, magnetic properties.\u00a0<\/p>\n

Professor David Mills<\/a>, Professor of Inorganic Chemistry at The University of Manchester, said:\u00a0“The best single-molecule magnets reported over the past decade have tended to excel in different areas. Our goal was to bring the most successful features of these designs together in a single molecule. By carefully controlling the structure around the dysprosium centre, we’ve produced materials that perform strongly across several key measures of magnetic memory.”\u00a0<\/p>\n

The international team, led by Professor David Mills at Manchester and Professor Nicholas Chilton at the Australian National University, combined cyclopentadienyl ligands, which help create rigid molecular structures, with amide ligands, which form particularly short dysprosium-nitrogen bonds. The resulting molecules adopted\u00a0near-linear structures with ligand angles approaching 172\u00b0, a geometry believed to contribute\u00a0in part\u00a0to their exceptional magnetic behaviour.\u00a0\u00a0<\/p>\n

Alongside\u00a0magnetic\u00a0hysteresis temperatures of up to 92 K, the new materials\u00a0were able to store magnetic information for a hundred seconds\u00a0up to\u00a0a temperature of\u00a040 K,\u00a0indicating\u00a0significantly improved retention of magnetic memory compared with earlier dysprosium-amide systems.\u00a0\u00a0<\/p>\n

Professor\u00a0David\u00a0Mills\u00a0continued:\u00a0\u201cControlling the geometries of lanthanide compounds is notoriously difficult as the chemical bonding is non-directional. Therefore, although near-linear dysprosium compounds have long been predicted to give the best SMMs, we are only now able to use carefully selected combinations of ligands to consistently deliver these target molecules.\u201d\u00a0<\/p>\n

The ability to create\u00a0SMMs\u00a0with\u00a0magnetic memory effects at\u00a0higher\u00a0temperatures\u00a0widens\u00a0the opportunity\u00a0for these molecules to be used for high-density data storage\u00a0devices,\u00a0which is\u00a0important for the\u00a0ever-increasing\u00a0amount of data\u00a0storage\u00a0required\u00a0in\u00a0for our technological age.\u00a0\u00a0<\/p>\n
