Abstract
We studied the magnetic ordering of thin films and bulk crystals of rutile RuO₂ using resonant x-ray scattering across the Ru L₂ absorption edge. Combining polarization analysis and azimuthal angle dependence of the magnetic Bragg signal, we have established the presence and characteristic of collinear antiferromagnetism in RuO₂ with T_{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 in antiferromagnetic spintronics.
