Abstract: B35.00005 : The Functionality of a Topological Chiral Antiferromagnet Mn3X (X=Sn, Ge)
1:54 PM–2:30 PM
In the first half of this talk, we will introduce our recent experimental results on the magnetic spin Hall effects (MSHE), particularly angular dependent spin densities appearing on the surface of a focused ion beam fabricated Mn3Sn epitaxial thin slab. We will discuss the new functionality for magnetic manipulation we could obtain from the MSHE. In the second half, we will discuss the electrical nucleation, displacement, and detection of antiferromagnetic domain walls (AFDWs) consisting of the CMOPs. We will also show some of our recent MOKE measurements for Mn3Ge to discuss the magnetic domain structures. Our findings could provide a guiding principle for engineering the AFDW structure in the chiral antiferromagnetic materials.
