LiOsO3 is the first experimentally confirmed polar metal. Previous works suggested that the ground state of LiOsO3 is just close to the critical point of metal-insulator transition. In this work the electronic state of LiOsO3 is tuned by epitaxial biaxial strain, which undergoes the Slater-type metal-insulator transition under tensile strain, i.e., the G-type antiferromagnetism emerges. The underlying mechanism of bandwidth tuning can be extended to its sister compound NaOsO3, which shows an opposite transition from a antiferromagnetic insulator to a nonmagnetic metal under hydrostatic pressure. Our work suggests a feasible route for the manipulation of magnetism and conductivity of polar metal LiOsO3.
