Laser‐Induced Creation of Antiferromagnetic 180‐Degree Domains in NiO/Pt Bilayers

We demonstrate how the antiferromagnetic order in heterostructures of NiO/Pt thin films can be modified by optical pulses. irradiate our samples with laser light and identify an optically induced creation domains imaging created domain structure utilizing X-ray magnetic linear dichroism effect. study effect different polarizations on formation a polarization-independent 180{\deg} walls N\'eel vector orientation. By varying irradiation parameters, we determine switching mechanism to thermally reversibility. thus experimentally possibility create domains, important step towards future functionalization all mechanisms antiferromagnets.
