Evidence of tetragonal distortion as the origin of the ferromagnetic ground state in $\gamma$−Fe nanoparticles

$\gamma$−Fe and related alloys are model systems of the coupling between structure and magnetism in solids. Since different electronic states (with different volumes and magnetic ordering states) are closely spaced in energy, small perturbations can alter which one is the actual ground state. Here,...
