abstract = {Motivated by the recently observed topological Hall effect
in ultra-thin films of SrRuO3 (SRO) grown on the SrTiO3
[001] substrate, we investigate the magnetic ground state
and anomalous Hall response of the SRO ultra-thin films by
virtue of spin density functional theory (DFT). Our findings
reveal that in the monolayer limit of an SRO film, a large
energy splitting of Ru-t2g states stabilizes an
anti-ferromagnetic (AFM) insulating magnetic ground state.
For the AFM ground state, our Berry curvature calculations
predict a large anomalous Hall response upon doping. From
the systematic symmetry analysis, we uncover that the large
anomalous Hall effect arises due to a combination of broken
time-reversal and crystal symmetries caused by the
arrangement of non-magnetic atoms (Sr and O) in the SRO
monolayer. We identify the emergent Hall effect as a clear
manifestation of the so-called crystal Hall effect in
terminology of Šmejkal et al., Crystal Hall effect in
collinear antiferromagnets (2019), and demonstrate that it
persists at finite frequencies, which is the manifestation
of the crystal magneto-optical effect. Moreover, we find a
colossal dependence of the anomalous Hall effect on the
degree of crystal symmetry breaking also in ferromagnetic
SRO films, which all together points to an alternative
explanation of the emergence of the topological Hall effect
observed in this type of systems.},
