  Density functional theory is a standard model for condensed matter theory and
computational material science. The accuracy of density functional theory is
limited by accuracy of the employed approximation to the exchange-correlation
functional. Recently, the so-called strongly constrained approprietly normed
(SCAN) functional has received a lot of attention due to promising results for
covalent, metallic, ionic, as well as hydrogen- and van der Waals-bonded
systems alike. In this work we focus on assessing the performance of the SCAN
functional for itinerant magnets by calculating basic structural and magnetic
properties of the transition metals Fe, Co and Ni. We find that although
structural properties of bcc-Fe seem to be in good agreement with experiment,
SCAN performs worse than standard local and semilocal functionals for fcc-Ni
and hcp-Co. In all three cases, the magnetic moment is significantly
overestimated by SCAN, and the $3d$ states are shifted to lower energies, as
compared to experiments.
