Query: Ferroelectric control of N\'eel vector in L10 type of antiferromagnetic
  films   How to efficiently manipulate the N\'eel vector of antiferromagnets (AFM) by
electric methods is one of the major focuses in current antiferromagnetic
spintronics. In this work, we investigated the ferroelectric control of
magnetism in AFM L10-MnPt/BaTiO3 bilayers structures by using first-principles
calculation. We studied the effect of ferroelectric polarization reversal on
magnetic crystalline anisotropy (MCA) of L10-MnPt films with different
interface structures. Our results predict a large perpendicular MCA in L10-MnPt
films with Pt-O interface, while an in-plane MCA with Mn-O interface when they
are interfaced with ferroelectric BaTiO3. In addition, the magnitude of MCA for
both interfaces can be modulated efficiently by the polarization reversal of
BaTiO3. The ferroelectric control of MCA has been analyzed based on second
order perturbation theory, and it can be mainly attributed to the ferroelectric
polarization driven redistribution of Pt-5d orbital occupation around Fermi
energy. Especially, for Mn-O interface, the N\'eel vector can be switched
between in-plane [100] and [110] directions, or even from in-plane to
out-of-plane at certain film thickness by reversing ferroelectric polarization.
Our results may provide a non-volatile concept for ferroelectric control of
N\'eel vector in L10-antiferromagnets, which could stimulate experimental
investigations on magnetoelectric effect of antiferromagnets and promote its
applications in low-power consumption spintronic memory devices.
