Direct observation of a spin-polarized surface Dirac gap in the antiferromagnetic topological insulator NdBi
Yuto Fukushima, Hiroyuki S. Suzuki, Masayuki Ochi +15
A gapped Dirac cone in antiferromagnetic topological insulators (AFM-TIs) is essential for realizing the quantized anomalous Hall effect, yet its intrinsic magnitude remains contro…
Impact of the out-of-plane conductivity on spin transport evaluation in a van der Waals material
Ryoya Nakamura, Futo Tokuda, Yoshinobu Ono +5
Layered materials are promising candidates for spintronic applications due to their unique electronic structures and spin transport properties. However, the strong anisotropic cond…
Electronic band structure, phonon dispersion, and magnetic triple-q state in GdGaI
Tatsuya Kaneko, Ryota Mizuno, Shu Kamiyama +2
We theoretically investigate the physical properties of the magnetic van der Waals material GdGaI. Using first-principles calculations, we compute the phonon dispersion of GdGaI an…
Transport evidence of current-induced nematic Dirac valleys in a parity-time-symmetric antiferromagnet
H. Sakai, Y. Miyamoto, M. Kimata +6
Itinerant antiferromagnets with broken time-reversal symmetry have recently attracted attention, since their spin-split bands enable large magnetotransport responses comparable to…
A robust weak topological insulator in a bismuth halide Bi4Br2I2
Ryo Noguchi, Masaru Kobayashi, Kaishu Kawaguchi +11
We apply a topological material design concept for selecting a bulk topology of 3D crystals by different van-der-Waals stacking of 2D topological insulator layers, and find a bismu…
