Abstract

While ruthenium dioxide has been cited as the canonical realization of the altermagnetic state, many recent experimental probes are at odds. Here, the authors demonstrate that transport in single crystals shows no sign of a transition to an altermagnetic state over an extended temperature range up to 1000 $K$ and that the magnetotransport in single crystals is dominated by multiband effects.
