Altermagnetic XMCD in Hematite Distinct from Weak Ferromagnetic Contributions
Y. Ishii, N. Sasabe, Y. Yamasaki
Altermagnets are compensated collinear magnets that break time-reversal symmetry without net magnetization, enabling unconventional magneto-optical responses. Here, altermagnetic X…

Quintuplet condensation in the skyrmionic insulator Cu2OSeO3 at ultrahigh magnetic fields
T. Nomura, I. Rousochatzakis, O. Janson +6
We report ultrahigh magnetic field Faraday rotation results on the chiral helimagnet Cu2OSeO3, the first Mott insulator showing skyrmion lattice phases and a linear magnetoelectric…

Gradual charge order melting in Bi0.5Ca0.5MnO3 induced by ultrahigh magnetic field
Y. Ishii, A. Ikeda, M. Tokunaga +3
We have investigated the magnetic properties of Bi0.5Ca0.5MnO3 under ultrahigh magnetic fields by magnetization measurements. This compound shows the metamagnetic transition which…
