Abstract

Our ongoing spectroscopic survey of high proper motion stars is a rich source of new magnetic white dwarfs. We present a few examples among cool white dwarfs showing the effect of field strength and geometry on the observed optical spectrum. Modelling of hydrogen and heavy element spectral lines reveals a range of uniform or markedly offset dipole fields in these objects.
