Scientific paper

We report the detection of modulated circular polarization in V795 Her. The
degree of polarization increases with wavelength and is modulated with a period
of 19.54 min, which is very close to the reported optical QPO period. The
modulation has a peak-to-peak amplitude of 0.12% in the U-band. The estimated
magnetic field intensity is in the range 2-7 MG.
