We report on seven peculiar faint blue stars found in the course of the Hamburg/ESO survey (HES) which appear to be magnetic white dwarfs (WDs) with non-hydrogen spectra. We show in particular that four of them (HE 0338-3853, HE 0107-0158, HE 0026-2150, and HE 0003-5701) have HeI lines split by magnetic fields of roughly 20MG, since the π components of HeI 5876Å and HeI 4929Å can be identified unambiguously in their spectra, and the σ⁺, σ^– components can be identified in the spectra of two of these stars (HE 0338-3853 and HE 0003-5701). Besides GD 229, these are the first magnetic DB white dwarfs discovered so far. In addition, three further WDs with broad, unidentifiable features have been found: HE 1043-0502, HE 0236-2656, and HE 0330-0002. We argue that in all three of these stars HI can not be responsible for the broad features, and HeI most probably not for the features in HE 0236-2656 and HE 0330-0002, while it still remains possible that the broad features of HE 1043-0502 are due to HeI.
