摘要

Antiferromagnetic (AFM) materials, with robust rigidity to magnetic field perturbations and ultrafast spin dynamics, show great advantages in information storage and have developed into a fast-emerging field of AFM spintronics. However, a direct characterization of spin alignments in AFM films has been challenging, and their manipulation by lattice distortion and magnetic proximity is inevitably accompanied by "ferromagnetic" features within the AFM matrix. Here we resolve the G-type AFM structure of SrCoO2.5 and find that the interfacial AFM structure could be modulated intrinsically from in plane to out of plane with a canted angle of 60 by the charge transfer and orbital reconstruction in SrCoO2.5/La2/3Sr1/3MnO3 heterostructures both experimentally and theoretically. Such an interfacial AFM reconfiguration caused by electronic reconstruction does not cause the ferromagnetic feature and changes the magnetization switching process of La2/3Sr1/3MnO3 from in plane to perpendicular to the plane, in turn. Our study not only reveals the coupling between charge, orbital, and AFM structure, but also provides a unique approach to manipulating AFM structure.
