In a new publication in Nature Materials, an international team of researchers has developed groundbreaking artificial chains of the iconic "olympicene" molecules to realize the antiferromagnetic (AF) ...

When most people hear "polymer," they think of plastics. In our group, polymerization is a way to line up identical molecules like beads on a string and let quantum mechanics take over. Put magnetic ...

In these chains, the magnetic moments align in an antiparallel manner but do not completely cancel out. Also of great interest are two-dimensional spin lattices, which exhibit a much greater variety ...

Neutron scattering is considered the method of choice for investigating magnetic structures and excitations in quantum materials. Now, for the first time, the evaluation of measurement data from the ...

This is a spin chain in which spin interactions are strong in the left half (orange arrows) and weak in the right half (blue arrows). A spin current from left to right (green arrowed line) is possible ...

For the homogeneous Heisenberg chain, the researchers used the nanographene molecule Olympicen, which consists of five carbon rings. In 2024, Empa researchers and their partners successfully for the ...
