Jason Haraldsen of UNF has investigated the electronic changes in zinc telluride and made it magnetic by replacing tellurium with manganese. This made the material become a spin-glass, a magnetic state below a specific, very cold temperature.
Spin-glass materials have the potential to enhance technology through energy-efficient magnetic memory. Haraldsen’s findings indicate that the spin-glass transition temperature depends on specific electron interactions. If those interactions can be altered, it may be possible to control the spin-glass state for technological applications.
