  A family of modified Nicole models is introduced. We show that for particular
members of the family a topological soliton with a non-trivial value of the
Hopf index exists. The form of the solitons as well as their energy and
topological charge is explicitly found. They appear to be identical as the
so-called eikonal knots. The relation between energy and topological charge of
the solution is also presented. Quite interesting it seems to differ
drastically from the standard Vakulenko-Kapitansky formula.
