Abstract
Measurements of the general magnetic fields of active, late-type stars obtained with the 2.6-m Sha\(\overset{\lower0.5em\hbox{$\smash{\scriptscriptstyle\smile}$}}{l} \)n telescope of the Crimean Astrophysical Observatory are reported. Statistically significant values of the magnetic fields of ∈ Eri and 61 Cyg A have been detected. The magnetic fields range from −10 to 21 G. The magnetic-field values for ∈ Eri and 61 Cyg A exceed the solar field by an order of magnitude; ∈ Eri is more active than the Sun, while 61 Cyg A has approximately the same activity level as the Sun. There is some evidence for variations in the general magnetic fields of these stars associated with their axial rotation.
