DESCRIPTION:Speakers: Masatoshi Hiraishi (Ibaraki University)\nRuthenium d
 ioxide RuO$_2$ is a well-known catalyst applied in various fields due to i
 ts high electrical conductivity and chemical stability. Although rutile Ru
 O$_2$ has long been regarded as a Pauli paramagnetic metal\, recent neutro
 n diffraction experiments and resonant X-ray scattering have suggested the
  presence of an antiferromagnetic order ($T_\\mathrm{N}>300~$K: Ru moment 
 size $\\sim$0.05$~\\mu_\\mathrm{B}$) associated with the lattice distortio
 n. This has triggered a growing interest regarding the details of the elec
 tronic state. We were thus motivated to investigate the magnetic ground st
 ate of high-quality single crystal RuO$_2$ (residual resistivity ratio RRR
 >1\,000) by muon spin rotation/relaxation experiment. We found no clear ev
 idence from $\\mu$SR measurements to suggest the development of a quasi-st
 atic antiferromagnetic order from $400~$K to $4~$K. The remaining possibil
 ity is that the muons happen to reside at a site where the internal magnet
 ic field is canceling. In the presentation\, we will also report the evalu
 ation of muon site in the rutile structure deduced by first principles cal
 culations to examine this possibility.\n\nhttps://indico.stfc.ac.uk/event/
