Researchers from the Trinity College in Dublin, Ireland, found out that Organic molecules can exhibit n-type magnetism. They say that conjugated polymers make strong candidates for future spintronic applications.

While organic compounds are interesting for spintronics due to their extremely long spin lifetimes (because of weak spin relaxation effects), it's not very easy to manipulate the spin orientation in organic spin devices. The new class of molecules (known as spin crossover compounds) may solve this issue as their spin state can be changed from low spin to high spin by an external perturbation.
