Magnetic Dichroism in Rutile NiF${}_2$: Separating Altermagnetic and Ferromagnetic Effects

A. Hariki, K. Sakurai, T. Okauchi +1

We present numerical simulations of x-ray magnetic circular dichroism (XMCD) at the L${}_{2,3}$ edge of Ni in the weakly ferromagnetic altermagnet NiF${}_2$. Our results predict a sign…
