Abstract
Plastic deformation of CoO has been performed at 4.2 K by compression of single crystals along <100>. The influence of thermodynamic conditions of specimen preparation has been shown. The dislocation structure observed by transmission electron microscopy (TEM) is not directly related to the one existing during deformation at very low temperature.
Résumé
On a déformé plastiquement CoO à 4,2 K par compression de monocristaux le long de <100>. L'influence des conditions thermodynamiques de préparation des échantillons a été montrée. La structure des dislocations observée en microscopie électronique en transmission (TEM) n'est pas directement reliée à celle existant pendant la déformation à très basse température.
