Topological magnonic properties of an antiferromagnetic chain
Topojit Debnath, Shri Hari Soundararaj, Sohee Kwon +2
The magnonic excitations of a dimerized, one-dimensional, antiferromagnetic chain can be trivial or topological depending on the signs and magnitudes of the alternating exchange co…
Evolution of Berry Phase and Half-Metallicity in CrTe in Response to Strain, Filling, Thickness, and Surface Termination
Sohee Kwon, Yuhang Liu, Hang Chi +3
CrTe is a ferromagnetic, quasi-two-dimensional layered material with perpendicular magnetic anisotropy, strong spin-orbit coupling, and non-trivial band topology. The non-t…
Structural, electronic, and magnetic properties of CrTe2
Yuhang Liu, Sohee Kwon, George J. de Coster +2
Two-dimensional chromium ditelluride (CrTe2) is a promising ferromagnetic layered material that exhibits long-range ferromagnetic ordering in the monolayer limit. The formation ene…
Structural tuning magnetism and topology in a magnetic topological insulator
Christopher Eckberg, Gang Qiu, Tao Qu +10
To date, the most widely-studied quantum anomalous Hall insulator (QAHI) platform is achieved by dilute doping of magnetic ions into thin films of the alloyed tetradymite topologic…
Strain-tunable Berry curvature in quasi-two-dimensional chromium telluride
Hang Chi, Yunbo Ou, Tim B. Eldred +22
Magnetic transition metal chalcogenides form an emerging platform for exploring spin-orbit driven Berry phase phenomena owing to the nontrivial interplay between topology and magne…
Effects of filling, strain, and electric field on the Néel vector in antiferromagnetic CrSb
In Jun Park, Sohee Kwon, Roger K. Lake
CrSb is a layered antiferromagnet (AFM) with perpendicular magnetic anisotropy, a high Néel temperature, and large spin-orbit coupling (SOC), which makes it interesting for AFM spi…
