Control of helix orientation in chiral magnets via lateral confinement
Maurice Colling, Mariia Stepanova, Mario Hentschel +7
Helimagnetic materials offer a versatile platform for spin-based device concepts owing to their long-range, tunable spiral order. Here, we demonstrate controlled manipulation of th…
Two-dimensional superconducting diode effect in topological insulator/superconductor heterostructure
Soma Nagahama, Yuki Sato, Minoru Kawamura +7
The superconducting diode effect (SDE) is characterized by the nonreciprocity of Cooper-pair motion with respect to current direction. In three-dimensional (3D) materials, SDE resu…
Quantum geometry in low-energy linear and nonlinear optical responses of magnetic Rashba semiconductor (Ge,Mn)Te
Tsubasa Takagi, Hikaru Watanabe, Ryutaro Yoshimi +7
Quantum geometry appears as a key factor in understanding the optical properties of quantum materials, with the anticipation on diverging or quantized responses near the Dirac and…
Electric-field control of two-dimensional ferromagnetic properties by chiral ionic gating
Hideki Matsuoka, Amaki Moriyama, Tomohiro Hori +5
Chiral molecular systems offer unique pathways to control spin and magnetism beyond conventional symmetry operations. Here, we demonstrate that chiral ionic liquids enable electric…
Control of nonreciprocal charge transport in topological insulator/superconductor heterostructures with Fermi level tuning and superconducting-layer thickness
Soma Nagahama, Yuki Sato, Minoru Kawamura +7
Nonreciprocal charge transport (NCT) is defined as a phenomenon where electrical resistance depends on the current direction. It has been drawing much attention because it sensitiv…
AC Current-Driven Magnetization Switching and Nonlinear Hall Rectification in a Magnetic Topological Insulator
Yuto Kiyonaga, Masataka Mogi, Ryutaro Yoshimi +7
Spin-orbit torque arising from the spin-orbit-coupled surface states of topological insulators enables current-induced control of magnetization with high efficiency. Here, alternat…
