Ferroelectricity driven-resistive switching and Schottky barrier modulation at CoPt/MgZnO interface for non-volatile memories
Mohamed Belmoubarik, Muftah Al-Mahdawi, George Machado +4
Ferroelectric memristors have attracted much attention as a type of nonvolatile resistance switching memories in neuromorphic computing, image recognition, and information storage.…
Control of sensitivity in vortex-type magnetic tunnel junction magnetometer sensors by the pinned layer geometry
Motoki Endo, Muftah Al-Mahdawi, Mikihiko Oogane +1
The tuning of sensitivity and dynamic range in linear magnetic sensors is required in various applications. We demonstrate the control and design of the sensitivity in magnetic tun…
Quadratic magnetoelectric effect during field cooling in sputter grown CrO films
Muftah Al-Mahdawi, Tomohiro Nozaki, Mikihiko Oogane +3
CrO is the archetypal magnetoelectric (ME) material, which has a linear coupling between electric and magnetic polarizations. Quadratic ME effects are forbidden for the mag…
