Molecular magnets

Materials science is a developing field that involves the design and synthesis of compounds with novel properties. Towards this goal, European researchers worked on nanoscopic magnets.
Molecular magnets
Nanoscopic magnetic materials are of increasing interest because of their potential use in biomedical and information storage applications. Single-molecule magnets (SMMs) represent promising candidates of magnetic materials that retain their magnetisation at the molecular level in the absence of an applied field.

For this purpose, it is important to achieve SMM preparations with larger thermodynamic barriers and effective (kinetic) barriers to magnetisation reversal. To realise this, scientists on the EU-funded MN-LN SMMS (Synthesis and characterization of Mn-Ln polynuclear complexes with interesting magnetic properties by the use of diol type ligands) project proposed to combine manganese (Mn), lanthanide (Ln) and diol-type ligands. Therefore, they worked to synthesise and characterise new compounds that contain such elements.

Overall, scientists isolated and characterised 49 compounds, 24 of which were Mn-Ln heterometallic clusters bearing diol-type ligands. To do so, they developed a new synthetic methodology targeting heterometallic Mn-Ln clusters. The majority of the generated compounds represented unprecedented structural types and contained interesting magnetic properties.

Taken together, the activities of the MN-LN SMMS study contributed towards the structural modification of compounds in order to achieve optimal SMM properties. The generated tools will be very useful in future materials science studies for producing novel compounds for various applications.
