Direct Observation of Vortices and Antivortices Generation in Phase-Separated Superconductor Sn-Pb Solder
Hiroto Arima, Takumi Murakami, Yuto Kinoshita +4
Quantized vortices in type-II superconductors provide insights into the mechanisms of superconductivity. However, the generation of antivortices, characterized by magnetization ant…
Nonvolatile magneto-thermal switching driven by vortex trapping in commercial In-Sn solder
Poonam Rani, Takumi Murakami, Yuto Watanabe +4
Magneto-thermal switching (MTS) is a key technology for efficient thermal management. Recently, large MTS with nonvolatility has been observed in Sn-Pb solders [H. Arima et al., Co…
Superconducting properties and electronic structure of CuAl2-type transition-metal zirconide Fe1-xNixZr2
Ryunosuke Shimada, Yuto Watanabe, Lorenzo Tortora +8
CuAl2-type transition-metal (Tr) zirconides are superconductor family, and the Tr-site element substitution largely modifies its transition temperature (Tc). Here, we synthesized p…
Large self-heating by trapped-flux reduction in Sn-Pb solders
Yoshikazu Mizuguchi, Takumi Murakami, Md. Riad Kasem +1
Magnetic flux trapping in field-cooled (FC) Sn-Pb solders has been recently studied because of the observation of nonvolatile magneto-thermal switching [H. Arima et al., Commun. Ma…
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…
Magnetic field hysteresis of thermal conductivity in type-I and typy-II superconductors
Hiroto Arima, Miku Yoshida, Yoshikazu Mizuguchi
This study investigated the magnetic field () dependence of thermal conductivity () in type I (Pb) and type II (Nb) superconductors. The of Nb displayed hysteresis, showi…
