, In the case of -20V (a), the spins point outwards (left-handed chirality) while in the +80V(e) case, with opposite DMI sign, an opposite chirality (right-handed chirality) is stabilized. In this latter case however, the domain walls are not completely Néel type. For +88V(f) a perfect right handed Néel type skyrmion is obtained. We also show that at intermediate voltage: +37V (d), where the magnetization configuration of the skyrmion becomes Bloch-like with no preferred chirality as DMI is close to zero at this voltage.
