Possibility of ferro-octupolar order in BaCaOsO assessed by X-ray magnetic dichroism measurements
Goro Shibata, Naomi Kawamura, Jun Okamoto +9
Localized electrons in a cubic crystal field possess multipoles such as electric quadrupoles and magnetic octupoles. We studied the cubic double perovskite BaCaOsO c…

Absence of transport altermagnetic spin-splitting effect in RuO2
Yu-Chun Wang, Zhe-Yu Shen, Chia-Hsi Lin +8
Altermagnets, which exhibit the advantages of both antiferromagnets and ferromagnets, have attracted significant attention recently. Among them, ruthenium dioxide (RuO2), a prototy…

Giant X-ray circular dichroism in a time-reversal invariant altermagnet
Jun Okamoto, Ru-Pan Wang, Yen-Yi Chu +13
X-ray circular dichroism, arising from the contrast in X-ray absorption between opposite photon helicities, serves as a spectroscopic tool to measure the magnetization of ferromagn…
