Abstract
The fractal nature of the magnetic field fluctuations is verified usin g HEOS 2 (at 1 AU), Pioneer 10 (at 4.8 AU), Pioneer 11 (at 20 AU) inte rplanetary and ICE (Giacobini-Zinner) cometary environment high resolu tion measurements. The fractal dimension of the time series profiles i s estimated and the self-affinity property is tested. The results show significant diversions from the power-law model. Certain properties o f the field scaling, exhibited in most of the cases, indicate that det erministic, chaotic dynamics may exist in the solar wind turbulence.
