Thermal rectification in jointless Pb solid wire
Masayuki Mashiko, Poonam Rani, Yuto Watanabe +1
Thermal rectification is observed in jointless Pb wires at temperatures near the superconducting transition of Pb under magnetic fields. Using different magnetic-field (H) response…
Uniaxial negative thermal expansion in a weak-itinerant-ferromagnetic phase of CoZrH
Yuto Watanabe, Kota Suzuki, Takayoshi Katase +3
We discovered unique uniaxial negative thermal expansion (NTE) behavior for a weak-itinerant-ferromagnetic phase of CoZrH. CoZr is known as a superconductor ex…
Huge anisotropic magneto-thermal switching in high-purity polycrystalline compensated metals
Poonam Rani, Yuto Watanabe, Takuma Shiga +6
Magneto-thermal transport is a promising physical property for thermal management applications. Magneto-thermal switching enables active control of heat flows, and a high switching…
Vortex formation and exotic superconducting states in field-cooled Sn-Pb solders
Takumi Murakami, Md. Riad Kasem, Hiroto Arima +3
Formation of vortices is a typical phenomenon of type-II superconductors under magnetic fields (H). In contrast, type-I superconductors do not host vortices because of their Meissn…
