Unconventional two-dimensional quantum oscillations in three-dimensional thick SrRuO$_3$ films
SrRuO$_3$ is a prototypical transition metal oxide which hosts rich physical
properties including itinerant ferromagnetism, high conductivity, and intrinsic
Hall effect originating in the Weyl points. Recently, high-quality SrRuO$_3$
films with residual resistivity ratios of more than 50 have been reported to
exhibit quantum oscillations at low temperatures in spite of its strong
electron correlation. While the origin of the oscillations has been discussed
in relation to Weyl orbits based on the Weyl semimetal band structure, so far
experimentally reported results are neither consistent with each other nor with
theoretically expected behavior, leaving the origin of the oscillations in
SrRuO$_3$ films still elusive. In this report, we have carefully evaluated the
quantum oscillations observed in three-dimensional thick SrRuO$_3$ films with a
high residual resistivity ratio of RRR = 82. We reveal the coexistence of two
oscillation components both derived from two-dimensional electronic states and
with slightly different masses, suggesting the involvement of the surface Fermi
arc states formed between different Weyl point pairs.
