Nonreciprocity reversal of magnetoacoustic attenuation in NiFe alloy thin films
Mingran Xu, Kei Yamamoto, Kouta Kondou +8
Nonreciprocity, the asymmetry of transport, underlies technologies from the diode to the microwave isolator. In a ferromagnet, a surface acoustic wave generates an elliptical effec…
Carrier-density dependence of magnetotransport in correlated Dirac semimetal CaIrO
Rinsuke Yamada, Jun Fujioka, Minoru Kawamura +8
We report the carrier density dependence of the magnetotransport property in the correlated Dirac semimetal CaIrO. In the dilute carrier density region ( $\sim 2.2 \…
High-temperature helical edge states in BiSbTeSe/graphene van der Waals heterostructure
Yoichi Tanabe, Ngoc Han Tu, Ming-Chun Jiang +11
Van der Waals heterostructures have been used to tailor atomic layers into various artificial materials through interactions at heterointerfaces. The interplay between the band gap…
Incommensurate broken helix induced by nonstoichiometry in the axion insulator candidate EuInAs
Masaki Gen, Yukako Fujishiro, Kazuki Okigami +9
Zintl phase EuInAs has garnered growing attention as an axion insulator candidate, triggered by the identification of a commensurate double- broken-helix s…
