  We present high-resolution spectropolarimetric observations of the
spectroscopic binary Chi Dra. Spectral lines in the spectrum of the main
component Chi Dra A show variable Zeeman displacement, which confrms earlier
suggestions about the presence of a weak magnetic field on the surface of this
star. Within about 2 years of time base of our observations, the longitudinal
component BL of the magnetic field exhibits variation from -11.5 +/- 2.5 G to
+11.1 +/- 2.1 G with a period of about 23 days. Considering the rotational
velocity of Chi DraA in the literature and that newly measured in this work,
this variability may be explained by the stellar rotation under the assumption
that the magnetic field is globally stable. Our new measurements of the radial
velocities (RV) in high-resolution I-spectra of Chi Dra A refined the orbital
parameters and reveal persistent deviations of RVs from the orbital curve. We
suspect that these deviations may be due to the in uence of local magnetically
generated spots, pulsations, or a Jupiter-size planet orbiting the system.
