Polar metals are commonly defined as metals with polar structural distortions. Strict symmetry restrictions make them an extremely rare breed as the structural constraints favor insulating over metallic phase. Moreover, no polar metals are known to be magnetic. Here we report on the realization of a magnetic polar metal phase in a BaTiO<sub>3</sub>/SrRuO<sub>3</sub>/BaTiO<sub>3</sub> heterostructure. Electron microscopy reveals polar lattice distortions in three-unit-cells thick SrRuO<sub>3</sub ...[more]
