  Magnetic chemically peculiar (mCP) stars exhibit complex atmospheres that
allow the investigation of the interplay of atomic diffusion, magnetic fields,
and stellar rotation. A non-uniform surface distribution of chemical elements
and the non-alignment of the rotational and magnetic axes result in the
variability of several observables. Photometrically variable mCP stars are
referred to as alpha2 Canum Venaticorum (ACV) variables. The present work
presents a case study of known variables from the Zwicky Transient Facility
(ZTF) survey, with the aim of investigating the survey's suitability for the
detection and study of new ACV variables. Using suitable selection criteria
based on the known characteristics of ACV variables, candidate ACV stars were
selected from the ZTF Catalog of Periodic Variable Stars. All light curves were
inspected in detail to select the most promising candidates. Where available,
low-resolution spectra from the LAMOST were employed to classify the stars on
the MK system and confirm their status as mCP stars. We have identified 86 new
promising ACV star candidates. 15 of these stars have LAMOST spectra available,
which, in all cases, confirm them as classical mCP stars, which highlights the
viability of our approach. The sample stars can be sorted into four subgroups
characterized by distinct light curve shapes. Anti-phase variations in
different photometric passbands, in particular, is a unique characteristic of a
subset of ACV stars readily usable for their identification. The availability
of data in three different passbands (g, r, and i) is a major advantage of the
ZTF survey. On the basis of our experience with other photometric surveys and
the analysis of light curves, we conclude that the ZTF is well suited for the
search for, and the analysis of, ACV variables, which, however, are not
considered in the available ZTF variable star catalogues.
