Abstract

We studied the magnetic ordering of thin films and bulk crystals of rutile RuO2_2 using resonant X-ray scattering across the Ru L2_2 absorption edge. Combining polarization analysis and azimuthal-angle dependence of the magnetic Bragg signal, we have established the presence of G-type antiferromagnetism in RuO2_2 with TN_N >> 300 K. In addition to revealing a spin-ordered ground state in the simplest ruthenium oxide compound, the persistence of magnetic order even in nanometer-thick films lays the ground for potential applications of RuO2_2 in antiferromagnetic spintronics.
