Extended Data Fig. 5: High-resolution transmission electron microscopy (HRTEM) images of Co20 fibre annealed at 523 K for 30 min.
From: Unprecedented non-hysteretic superelasticity of [001]-oriented NiCoFeGa single crystals
a–c, The HRTEM images taken along \([110]_{L2_1}\) and \([100]_{L2_1}\) zone axes show stripe features. d, The enlarged stripe of the HRTEM taken along \([110]_{L2_1}\) zone axis shows a partial collapse of the {111} planes along <111> direction of the body-centered cubic structure which results in the ω-like transition (the motif of L21 and ω-like structure are highlighted by magenta and blue rectangles respectively).
