Being "silent" means these molecules don't interfere with their neighbors, allowing them to be packed much more densely in a storage device than traditional magnets.
Unlike standard magnets that have a traditional north and south pole, SMTs possess a . This arises when individual magnetic moments (spins) within a molecule arrange themselves in a head-to-tail, vortex-like structure. This arrangement leads to some incredible "superpowers": 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. Being "silent" means these molecules don't interfere with
Most SMTs are built as triangles or rings (like the seminal Dy3cap D y sub 3 triangle) to facilitate the circular arrangement of spins. Single Molecule Toroics: Synthetic Strategies, ...
