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…
Wide-range resistivity and umklapp scattering in moiré graphene
Hiroaki Ishizuka, Leonid Levitov
We argue that the unusually strong electron-electron interactions in the narrow bands in moiré superlattices originate from compact Wannier orbitals. Enhanced overlaps of electroni…
Enhanced Electrical Magnetochiral Effect by Spin-hedgehog Lattice Structural Transition
Aki Kitaori, Naoya Kanazawa, Hiroaki Ishizuka +3
Nonreciprocal resistance, depending on both directions of current () and magnetic-field () or magnetization (), is generally expected to emerge in a chiral conductor, and…
Giant anomalous Hall effect from spin-chirality scattering in a chiral magnet
Yukako Fujishiro, Naoya Kanazawa, Ryosuke Kurihara +10
The electrical Hall effect can be significantly enhanced through the interplay of the conduction electrons with magnetism, which is known as the anomalous Hall effect (AHE). Wherea…
Spin-current version of solar cells in non-centrosymmetric magnetic insulators
Masahiro Sato, Hiroaki Ishizuka
Photovoltaic effect, e.g., solar cells, converts light into DC electric current. This phenomenon takes place in various setups such as in noncentrosymmetric crystals and semiconduc…
Butterfly-shaped magnetoresistance in triangular-lattice antiferromagnet AgCrO
Hiroki Taniguchi, Mori Watanabe, Masashi Tokuda +8
Spintronic devices using antiferromagnets (AFMs) are promising candidates for future applications. Recently, many interesting physical properties have been reported with AFM-based…
