Iron Atom under Strain (IMAGE) University of Warsaw, Faculty of Physics Caption The iron Fe2+ atom embedded in a semiconductor exhibits a single non-degenerate ground state with zero magnetic moment. A team of scientists from the University of Warsaw has just shown that by using sufficiently large strain (which is visualized here as an effect of a machine press) it is possible to tailor the energy spectrum of the iron atom to obtain doubly degenerate (magnetic) ground state. Such a state can be utilized for storage and processing of the quantum information. This discovery has been just published in prestigious research journal of Nature Communications.
