  Quantum oscillation (QO), a physical phenomenon that reflects the
characteristics of the Fermi surface and transport fermions, has been
extensively observed in metals and semimetals through various approaches, like
magnetostriction, magnetization, resistivity, and thermoelectric power.
However, only some allowed oscillation frequencies can be revealed by each
individual method, particularly in semimetals with intricate Fermi pockets and
associated magnetic breakdown phenomena. In this paper, we present the
application of an ac composite magnetoelectric (ME) technique to measure the
QOs of a topological nodal-line semimetal, ZrSiS, which possesses six
fundamental QO frequencies. By employing the ME technique with a maximum
magnetic field of 13 T and a minimum temperature of 2 K, we are able to capture
all the fundamental frequencies and most of the permissible magnetic breakdown
frequencies. In comparison, some of the frequencies were missing in the
aforementioned four methods under identical measurement conditions. Remarkably,
a series of magnetic breakdown frequencies around 8000 T were revealed even in
a magnetic field as low as 7.5 T. These findings highlight the ME technique as
an ultrahigh-sensitive tool for studying Dirac Fermions and other topological
semimetals with complex Fermi surfaces.
