Query: Zeeman effect in centrosymmetric antiferromagnets controlled by electric
  field   Centrosymmetric antiferromagnets, although abundant in nature, seem less
promising than ferromagnets or ferroelectrics for practical applications in
semiconductor spintronics. As a matter of fact, the lack of spontaneous
polarization and magnetization hinders the efficient utilization of electronic
spin in these materials. Here, we propose a paradigm to harness electronic spin
in centrosymmetric antiferromagnets via Zeeman spin splittings of electronic
energy levels -- termed as spin Zeeman effect -- which is controlled by an
electric field. By symmetry analysis, we identify twenty-one centrosymmetric
antiferromagnetic point groups that accommodate such a spin Zeeman effect. We
further predicted by first-principles that near-room temperature
antiferromagnetic SrFe$_2$S$_2$O is an excellent candidate showcasing a Zeeman
splitting as large as $\sim$75 meV, induced by an electric field of 0.15 V/\AA.
Moreover, the electronic spin magnetization associated to the split energy
levels is switchable when reversing the electric field. Our work thus sheds
light on the electric-field control of electronic spin in antiferromagnets,
which broadens the scope of application of centrosymmetric antiferromagnets.
