Quasi-two-dimensional Antiferromagnetic Spin Fluctuations in the Spin-triplet Superconductor Candidate CeRh$_2$As$_2$

Autor: Chen, Tong, Siddiquee, Hasan, Rehfuss, Zack, Gao, Shiyuan, Lygouras, Chris, Drouin, Jack, Morano, Vincent, Avers, Keenan E., Schmitt, Christopher J., Podlesnyak, Andrey, Ran, Sheng, Song, Yu, Broholm, Collin

The tetragonal heavy-fermion superconductor CeRh$_2$As$_2$ ($T_{\rm c}=0.3$ K) exhibits an exceptionally high critical field of 14 T for $\textbf{B} \parallel \textbf{c}$. It undergoes a field-driven first-order phase transition between superconducti

Autor: Avers, Keenan E., Eo, Yun Suk, Yoon, Hyeok, Horn, Jarryd A., Saha, Shanta R., Suarez, Alonso, Zavalij, Peter, Paglione, Johnpierre

Publikováno v: Phys. Rev. B 110, 134416 (2024)

FeSi is a curious example of a $d$-electron system that manifests many of the same phenomena associated with $f$-electron Kondo insulators, including conducting surface states with potentially non-trivial topology. Here we investigate the magnetizati

Extraordinary Bulk Insulating Behavior in the Strongly Correlated Materials FeSi and FeSb$_2$

Autor: Eo, Yun Suk, Avers, Keenan, Horn, Jarryd A., Yoon, Hyeok, Saha, Shanta, Suarez, Alonso, Fuhrer, Michael S., Paglione, Johnpierre

Publikováno v: Appl. Phys. Lett. 122, 233102 (2023)

4$f$ electron-based topological Kondo insulators have long been researched for their potential to conduct electric current via protected surface states, while simultaneously exhibiting unusually robust insulating behavior in their interiors. To this
