Spin-orbit-enabled Fermi-surface splitting in noncollinear antiferromagnetic SmBi
Long Zhang, Ming Cheng, Jingyu Li +10
Spin-split electronic structures in compensated antiferromagnets are commonly sought in the nonrelativistic limit, where magnetic order lifts spin degeneracy without spin-orbit cou…
Complex Temperature-dependent Thermal Conductivity in a Sawtooth Chain Magnet FeSiSe
Kunya Yang, Feihao Pan, Liran Wang +12
Geometrically frustrated magnets provide an ideal platform for exploring the interplay between lattice geometry and spin degrees of freedom. Here, we investigate the interactions b…
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…
Multiple Topological States in LaAgAs2, a Failed Square-Net Semimetal
Yang Liu, Tongrui Li, Xixi Yuan +15
The rational design of new materials emerges as an important direction to explore new topological materials, which is based on the understanding of the correlation between crystal…
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…
