Abstract : The distributions along a circle of constant declination of the linearly polarized radiation at a frequency of 1418 MHz from 68 extragalactic radio sources were examined. The effective resolution was about 0.8. At places within many sources very high degrees of polarization (> 15 per cent), usually accompanied by a constant plane of polarization, were found. Both facts imply the existence of a highly ordered magnetic field. Often other regions within the same source also contained uniform fields, but oriented differently. Less frequently the field is well-ordered over an entire component or even over the entire source. These regions of uniformity can exceed galactic dimensions (about 100 kpc). (Author)
