文摘

A baromagnetic effect in a novel tetragonal magnetic structure is introduced by vacancies in Mn₃Ga_0.95N_0.94, due to the change of the Mn–Mn distance and their spin re-orientation induced by a pressure field. This effect is proven for the first time in antiperovskite compounds by neutron powder diffraction analysis. This feature will enable wide applications in magnetoelectric devices and intelligent instruments.
