Determined by Resonant X-ray Scattering / Zhu, Z. h., Strempfer, J., Rao, R. r., Occhialini, C. a., Pelliciari, J., Choi, Y., Kawaguchi, T., You, H., Mitchell, J. f., Shao-Horn, Y., Comin, R.. - In: PHYSICAL REVIEW LETTERS. - ISSN 0031-9007. - 122:1(2019), pp. 1-7. [10.1103/physrevlett.122.017202]
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 TN>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.
