Selectable diffusion direction with topologically protected edge modes
Keita Funayama, Jun Hirotani, Atsushi Miura +1
Topological insulators provide great potentials to control diffusion phenomena as well as waves. Here, we show that the direction of thermal diffusion can be selected by the contri…
Strongly connected ex-situ MgB2 polycrystalline bulks fabricated by solid-state self-sintering
Hiroya Tanaka, Akiyasu Yamamoto, Jun-ichi Shimoyama +2
We have investigated the microstructure, normal-state electrical connectivity, and critical current density of ex-situ MgB2 polycrystalline bulks prepared by systematically varying…
Towards the Realization of Higher Connectivity in MgB2 Conductors: In-situ or Sintered Ex-situ?
A. Yamamoto, H. Tanaka, J. Shimoyama +3
The two most common types of MgB2 conductor fabrication technique - in-situ and ex-situ - show increasing conflicts concerning the connectivity, an effective current-carrying cross…
