Interplay between Interlayer Shift and Twist: Twisted van der Waals Nanowires Driven by Rotational Twinning
Dong-gyu Kim, Kisung Kang, Hani Kang +8
In van der Waals(vdW) layered materials, interlayer shift and twist have enabled the control of material properties through polytype and moire engineering. Various approaches, incl…
Temperature-dependent optical and magneto-optical spectra of ferromagnetic BCC Fe
Kisung Kang, David G. Cahill, André Schleife
Optical and magneto-optical properties of magnetic materials have been widely exploited to characterize magnetic structures and phenomena, however, their temperature dependence is…
Magnetic anisotropy in single-crystalline antiferromagnetic MnAu
Mebatsion S. Gebre, Rebecca K. Banner, Kisung Kang +4
Multiple recent studies have identified the metallic antiferromagnet MnAu to be a candidate for spintronic applications due to apparent in-plane anisotropy, preserved magnetic…
Angstrom-Scale Imaging of Magnetization in Antiferromagnetic FeAs via 4D-STEM
Kayla X. Nguyen, Jeffrey Huang, Manohar H. Karigerasi +6
We demonstrate a combination of computational tools and experimental 4D-STEM methods to image the local magnetic moment in antiferromagnetic FeAs with 6 angstrom spatial resolu…
High-resolution diffraction reveals magnetoelastic coupling and coherent phase separation in tetragonal CuMnAs
Manohar H. Karigerasi, Kisung Kang, Jeffrey Huang +6
Tetragonal CuMnAs was the first antiferromagnet where reorientation of the Néel vector was reported to occur by an inverse spin galvanic effect. A complicating factor in the format…
In-plane magnetic structure and exchange interactions in the high-temperature antiferromagnet Cr2Al
Chengxi Zhao, Kisung Kang, Joerg C. Neuefeind +2
The ordered tetragonal intermetallic CrAl forms the same structure type as MnAu, and the latter has been heavily investigated for its potential in antiferromagnetic spintro…
