Raman spectroscopy of van der Waals topological magnet GdGaI
Nan Jiang, Yijin Zhang, Yujie Xia +9
We report polarization-resolved Raman spectroscopy of a van der Waals compound GdGaI that is a candidate for excitonic insulators. By combining the symmetry analysis with density f…
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…
Zero-field superconducting diode effect induced by magnetic flux in a van der Waals superconductor trigonal PtBi
Nan Jiang, Masaki Maeda, Yuhi Yamaguchi +9
The superconducting diode effect is one of the nonreciprocal transport phenomena, where the critical current depends on the current direction. This effect is typically realized in…
Observation of the crossover from quantum fluxoid to half-quantum fluxoid in a chiral superconducting device
Masashi Tokuda, Fumiya Matsumoto, Noriaki Maeda +16
Topological superconductors are one of the intriguing material groups from the viewpoint of not only condensed matter physics but also industrial application such as quantum comput…
