Abstract: The current race into miniaturization of magnetic devices for information storage and processing is reaching the ultimate limit of few atoms per magnetic unit, a promising new route being offered by the exploitation of the spins of atoms organized in short chains. Functionalizing such spin segments requires a through characterization of their spin structure. To that purpose, we used polarized neutron diffraction on D3 and D19 to accurately measure the spin distribution along a chain of eight antiferromagnetically coupled magnetic ions. Our results show that the parity and topology of the chain govern the spin distribution under an applied magnetic field.
