Abstract
Chirality domains, within a helimagnet nucleated from the ferromagnetic phase, are shown to originate in the Bloch walls. Thermal cyclings suggest that these walls retain the chirality of the spiral domain. These stripe domains can be unstable on increasing the temperature, tending to those obtained from cooling from the paramagnetic phase.
