Antiferromagnetism in Bulk Rutile RuO$_2$

ORAL

Abstract

While bulk rutile RuO$_2$ has long been considered to be a Pauli paramagnet, we conclude it to host antiferromagnetism based on our combined theoretical and experimental study. This constitutes an important finding given the large amount of applications of RuO$_2$ in the electrochemical and electronics industry. Furthermore the high onset temperature of the antiferromagnetism around 1000K together with the high electrical conductivity makes RuO$_2$ unique among the ruthenates and among oxide materials in general.
