We have observed birefringent spirals induced by a field in a fingerprint texture of a cholesteric polymer in solution in a nematic low molar weight liquid crystal. This paper describes the conditions of nucleation of these spirals and the part of different parameters which determine their characteristics.Nous avons observé des spirales biréfringentes induites par un champ à partir d'une texture fingerprint résultante d'un polymère cholestérique en solution dans un cristal liquide nématique de faible poids molaire. Cet article décrit les conditions de nucléation de ces spirales et le rôle de différents paramètres qui déterminent leurs caractéristiques
