Low energy excitations in A-site ordered SmBaMn2O6
Mirian Garcia Fernandez, Abhishek Nag, Stefano Agrestini +5
The electron in a solid can be considered a bound state of the three independent, fundamental degrees of freedom creating quasi-particles: spinons, carrying the electron spin; plas…
orbital delocalization and magnetic collapse in superconducting (La,Pr)NiO films
Xiaoyang Chen, Wenliang Zhang, Fei Peng +20
The recent discovery of Ruddlesden--Popper (RP) nickelate thin-film superconductors has opened a new frontier in unconventional superconductivity. Its realization requires both com…
X-ray magnetic circular dichroism evidence of intrinsic -wave altermagnetism in rutile-structure NiF
Zezhong Li, Kosuke Sakurai, Yiu-Fung Chiu +13
We present the x-ray magnetic circular dichroism (XMCD) at the Ni -edge as an evidence of the -wave altermagnetism in rutile-structure NiF. Sizable XMCD signal is o…
Dominant apical-oxygen electron-phonon coupling in HgBaCaCuO
Wenshan Hong, Qizhi Li, Shilong Zhang +14
How electron-phonon interactions influence high-temperature superconductivity in cuprates remains contested, and their role outside the CuO planes has been largely overlooked.…
Circular Dichroism in Resonant Inelastic X-ray Scattering: Probing Altermagnetic Domains in MnTe
D. Takegami, T. Aoyama, T. Okauchi +11
X-ray magnetic circular dichroism provides a means to identify ferromagnetic, chiral, and altermagnetic orders via their time-reversal-symmetry () breaking. However, d…
