Interface-Confined Superconductivity with Thickness-Independent Superfluid Stiffness in (Pb,Sn)Te/FeTe Bilayers
Zi-Jie Yan, Hongtao Rong, Yiyuan Luo +12
Interface-induced superconductivity in FeTe-based heterostructures provides a promising route toward topological superconductivity, yet the roles of the neighboring layers topology…
Residual orbital magnetization governs the anomalous Hall effect in altermagnets
Yufei Zhao, Yiyang Jiang, Kamal Das +2
In altermagnets that exhibit anomalous Hall effect, the small remanent magnetization exists but has been treated as too small to be relevant to the Hall response. In this work, we…
Evaluating the Structural Basis for Polar Altermagnet Candidate Ca(Ru,Ti)O
Akash Saha, Yihuang Xiong, Vladimir A. Stoica +15
The interplay between polar and altermagnetic orders remains largely unexplored in the broader landscape of correlated electron systems. CaRuO has been proposed b…
Designing Strong and Broadband Nonreciprocal Thermal Radiation in Magnetic Topological Materials
Yiyang Jiang, Yufei Zhao, Linxiao Zhu +1
Breaking reciprocity in thermal radiation opens opportunities for energy harvesting, sensing, and thermal management. Traditional nonreciprocal radiative semiconductor devices need…
Imaging Surface Magnetization in Altermagnetic MnTe Films
Ling-Jie Zhou, Senlei Li, Zi-Jie Yan +13
Altermagnets with pronounced spin-splitting band structure, unconventional magnetic and crystal symmetries, and exotic magneto-transport properties have received immense interest i…
Millimeter-Scale, Atomically Controlled 2D Topological Insulators Revealed by Multimodal Spectroscopy
Woojoo Lee, Qiang Gao, Yufei Zhao +20
Quantum spin Hall insulators, or synonymously known as 2D topological insulators, are crucial 2D systems hosting topologically protected edge states. The working temperature of thi…
