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
