We explore emergent behavior of spatially confined magnetic materials including their dynamic and electronic transport properties.

Metamagnetic nanostructures

Emergent behavior in nanostructures featuring first-order phase transition from the antiferromagnetic to ferromagnetic state.

In case of FeRh the magnetic ordering is related to change in structure and other properties such as resistivity.
