In this work, we investigate the damage caused by the catastrophic breakdown of the insulating layer in TiN/Ti/HfO2/W memristors when subjected to ramped voltage stress. Our analysis includes physical and compositional examinations of the damaged regions using scanning electron microscopy (SEM) and energy-dispersive x-ray spectroscopy. [...]

Magneto-ionics-as the voltage-driven control of magnetic properties through ionic motion and redox processes-offers a promising route toward energy-efficient spintronic devices. Exchange bias, being the unidirectional anisotropy arising from interfacial coupling between antiferromagnets and ferromagnets, plays a central role in spintronics. [...]
