Gate-electric-field and magnetic-field control of versatile topological phases in a semi-magnetic topological insulator
Ryota Watanabe, Ryutaro Yoshimi, Kei S. Takahashi +4
Surface states of a topological insulator demonstrate interesting quantum phenomena, such as the quantum anomalous Hall (QAH) effect and the quantum magnetoelectric effect. Fermi e…
Theory of the microwave impedance microscopy of Chern insulators
Taige Wang, Chen Wu, Masataka Mogi +5
Microwave impedance microscopy (MIM) has been utilized to directly visualize topological edge states in many quantum materials, from quantum Hall systems to topological insulators,…
Nonreciprocal electrical transport in multiferroic semiconductor (Ge,Mn)Te
Ryutaro Yoshimi, Minoru Kawamura, Kenji Yasuda +4
We have investigated the nonreciprocal electrical transport, that is a nonlinear resistance effect depending on the current direction, in multiferroic Rashba semiconductor (Ge,Mn)T…
Experimental signatures of versatile Weyl semimetal in pyrochlore iridate with spin-ice like magnetic orders
Kentaro Ueda, Hiroaki Ishizuka, Markus Kriener +6
We report experimental signatures of topological transitions among the Weyl semimetal states of pyrochlore Pr2Ir2O7, where the Kondo coupling between the Ir topological electrons a…
Experimental signature of parity anomaly in semi-magnetic topological insulator
M. Mogi, Y. Okamura, M. Kawamura +9
A three-dimensional topological insulator features a two-dimensional surface state consisting of a single linearly-dispersive Dirac cone. Under broken time-reversal symmetry, the s…
Versatile electronic states in epitaxial thin films of (Sn-Pb-In)Te: from topological crystalline insulator and polar semimetal to superconductor
Ryutaro Yoshimi, Makoto Masuko, Naoki Ogawa +5
Epitaxial thin films of (SnPb)InTe were successfully grown by molecular-beam-epitaxy (MBE) in a broad range of compositions (0 x 1, 0 $\le…
