Magnetic-field-induced insulating behavior in black phosphorus under pressure
Kazuto Akiba, Yuzuki Sega, Yuichi Akahama +3
We investigated the out-of-plane magnetoresistance of pressurized black phosphorus (BP) with a longitudinal field configuration. Despite the absence of the Lorentz force in the pre…
Non-linear transport in field-induced insulating states of graphite
Masashi Tokunaga, Kazuto Akiba, Hiroshi Yaguchi +2
Graphite exhibits multi-stage phase transitions in the quantum-limit states realized by magnetic fields applied along the c-axis. Despite extensive studies on this phenomenon, the…
Realization of nodal ring semimetal in pressurized black phosphorus
Kazuto Akiba, Yuichi Akahama, Masashi Tokunaga +1
Topological semimetals are intriguing targets for exploring unconventional physical properties of massless fermions. Among them, nodal line or nodal ring semimetals have attracted…
Disordered Ground State and Magnetic Field-Induced Long-Range Order in an S=3/2 Antiferromagnetic Honeycomb Lattice Compound Bi3Mn4O12(NO3)
M. Matsuda, M. Azuma, M. Tokunaga +2
Bi3Mn4O12(NO3), in which the Mn4+ ions carry S=3/2, is the first honeycomb lattice system that shows no long-range magnetic order. Using neutron scattering, we have determined that…
