  We report the results of an observational study aimed at searching for
magnetic pulsating hot stars suitable for magneto-asteroseismology. A sample of
sixteen chemically peculiar stars was selected and analysed using both
high-resolution spectropolarimetry with ESPaDOnS and K2 high-precision space
photometry. For all stars, we derive the effective temperature, surface
gravity, rotational and non-rotational line broadening from our
spectropolarimetric data. High-quality K2 light curves were obtained for
thirteen of the sixteen stars and revealed rotational modulation, providing
accurate rotation periods. Two stars show evidence for roAp pulsations, and one
star shows signatures of internal gravity waves or unresolved g-mode
pulsations. We confirm the presence of a large-scale magnetic field for eleven
of the studied stars, of which nine are first detections. Further, we report
one marginal detection and four non-detections. Two of the stars with a
non-detected magnetic field show rotational modulation due to surface abundance
inhomogeneities in the K2 light curve, and we confirm that the other two are
chemically peculiar. Thus, these five stars likely host a weak (undetected)
large-scale magnetic field.
