Figure 2 (IMAGE) Tohoku University Caption The left side shows the thermal stability vs. temperature for the Hexa-MTJ developed in this study, and the conventional Double-interface MTJ. The right side displays the number of write cycles (endurance) of the Hexa-MTJ. The endurance of Hexa-MTJ exceeds at least 1 × 107, which is sufficient for eFlash applications Credit IEEE & Tohoku University Usage Restrictions Reporters may use freely these materials in news coverage with appropriate credit information.
