Evaluation of insulating behavior by Pb Substitution and Pressure-Induced Superconductivity in La2O2Bi3-xPb1+xS6
Rajveer Jha, Valenta Jarosla, Naohito Tsujii +6
We report synthesis, characterization, and physical properties of layered bismuth-sulfide compounds La2O2Bi3-xPb1+xS6. We synthesized a new La2O2Bi3PbS6 compound, whose crystal str…
Planar-type silicon thermoelectric generator with phononic nanostructures for 100 μW energy harvesting
Ryoto Yanagisawa, Sota Koike, Tomoki Nawae +10
Energy harvesting is essential for the internet-of-things networks where a tremendous number of sensors require power. Thermoelectric generators (TEGs), especially those based on s…
Strong phase coherence and vortex matter in a fractal system with proximity-induced superconductivity
Nanami Teramachi, Aoi Hashimoto, Iku Nakaaki +10
The proximity effect in normal/superconductor heterostructures is an intriguing phenomenon in that the normal side takes on the properties of a superconductor with an induced gap.…
Ferroelectricity induced by ferriaxial crystal rotation and spin helicity in a B-site-ordered double-perovskite multiferroic In2NiMnO6
Noriki Terada, Dmitry D. Khalyavin, Pascal Manue +5
We have performed dielectric measurements and neutron diffraction experiments on the double perovskite In2NiMnO6. A ferroelectric polarization, P ~ 30 μC/m2, is observed in a polyc…
Inversion-induced orbital and exchange disorders in antiferromagnetic A-site spinel CoAl2O4
Takashi Naka, Hiroaki Mamiya, Kanji Takehana +6
The inversion and volume effects on magnetism in a spinel-type magnetically frustrated compound, CoAl2O4, and its gallium-substituted system, CoAl2-xGaxO4, were investigated. Magne…
Unusual coexistence of negative/positive charge-transfer in mixed-valence NaCaCrO
M. Taguchi, H. Yamaoka, Y. Yamamoto +6
We have investigated the electronic structure of NaCaCrO using x-ray absorption spectroscopy together with Anderson impurity model calculations with full multip…
