Single Molecule Toroics: Synthetic Strategies, ... -

The surrounding organic molecules (ligands) must be perfectly positioned to force the metal ions' spins into that crucial head-to-tail alignment.

) is the gold standard for SMTs due to its high magnetic anisotropy—it has a very strong "preferred" direction for its spin. Single Molecule Toroics: Synthetic Strategies, ...

Because the spins cancel each other out in a circle, the molecule has no net magnetic dipole moment, making it invisible to most external magnetic fields. Single Molecule Toroics: Synthetic Strategies, ...
