ac strain based thermodynamic criterion for vortex lattice in type-II superconductors
Peipei Lu, Mengju Yuan, Jing Zhang +17
In type-I superconductors, zero electrical resistivity and perfect diamagnetism define two fundamental criteria for superconducting behavior. In contrast, type-II superconductors e…
Collective Resonance of Superconducting/Normal Domain Walls in the Intermediate State of type-I superconductor
Mengju Yuan, Yugang Zhang, Ying Zhu +5
The dynamics of phase boundaries, such as superconducting/normal (S/N) interfaces in type-I superconductors, are typically obscured in conventional magnetic measurements, which are…
Microstructure-controlled vortex phases and two-phase superconductivity in (TaNb)0.7(HfZrTi)0.5 revealed by ac magnetostrictive coefficients
Mengju Yuan, Yuze Xu, Bin Zhang +5
We investigate flux dynamics in the high-entropy alloy superconductor (TaNb)0.7(HfZrTi)0.5 after annealing (as-cast, 500 °C, 550 °C, and 1000 °C) using a sensitive ac composite…
Distinct Suppression Mechanisms of Superconductivity by Magnetic Domains and Spin Fluctuations in EuFe2(As1-xPx)2 superconductors
Mengju Yuan, Nan Zhou, Ruixia Ti +10
Using ac composite magnetoelectric technique, we map the phase diagrams of EuFe(As1-xPx)2 to resolve the interplay between superconductivity and ferromagnetism. For samples with Tc…
