Abstract
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. Herein, 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 an antiferromagnetic insulator to a nonmagnetic metal under hydrostatic pressure. A feasible route is suggested for the manipulation of magnetism and conductivity of polar metal LiOsO3.
