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.…
Exchange-biased quantum anomalous Hall effect
Peng Zhang, Purnima P. Balakrishnan, Christopher Eckberg +12
The quantum anomalous Hall (QAH) effect is characterized by a dissipationless chiral edge state with a quantized Hall resistance at zero magnetic field. Manipulating the QAH state…
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…
Large nonvolatile control of magnetic anisotropy in CoPt by a ferroelectric ZnO-based tunneling barrier
Muftah Al-Mahdawi, Mohamed Belmoubarik, Masao Obata +5
The electric control of magnetic anisotropy has important applications for nonvolatile memory and information processing. By first-principles calculations, we show a large nonvolat…
Search for the magnetic monopole at a magnetoelectric surface
Q. N. Meier, M. Fechner, T. Nozaki +11
We show, by solving Maxwell's equations, that an electric charge on the surface of a slab of a linear magnetoelectric material generates an image magnetic monopole below the surfac…
Finite-size scaling effect on Néel temperature of antiferromagnetic CrO-(0001) films in an exchange-coupled heterostructure
Satya Prakash Pati, Muftah Al-Mahdawi, Shujun Ye +3
The scaling of antiferromagnetic ordering temperature of corundum-type chromia films have been investigated. Néel temperature was determined from the effect of perpendicular…
Low-energy magnetoelectric control of domain states in exchange-coupled heterostructures
Muftah Al-Mahdawi, Satya Prakash Pati, Yohei Shiokawa +3
The electric manipulation of antiferromagnets has become an area of great interest recently for zero-stray-field spintronic devices, and for their rich spin dynamics. Generally, th…
Enhancing the blocking temperature of perpendicular-exchange biased Cr2O3 thin films using spacer and buffer layers
Naoki Shimomura, Satya Prakash Pati, Tomohiro Nozaki +2
In this study, we investigated the effect of spacer and buffer layers on the blocking temperature TB of the perpendicular exchange bias of thin Cr2O3 films, and revealed a high TB…
Critical behavior of sputter-deposited magnetoelectric antiferromagnetic CrO films near Néel temperature
Muftah Al-Mahdawi, Yohei Shiokawa, Satya Prakash Pati +3
Chromium(III) oxide is a classical collinear antiferromagnet with a linear magnetoelectric effect. We are presenting the measurements of the magnetoelectric susceptibility of a…
Low-non-linearity spin-torque oscillations driven by ferromagnetic nanocontacts
Muftah Al-Mahdawi, Yusuke Toda, Yohei Shiokawa +1
Spin-torque oscillators are strong candidates as nano-scale microwave generators and detectors. However, because of large amplitude-phase coupling (non-linearity), phase noise is e…
Formation and anisotropic magnetoresistance of Co/Pt nano-contacts through aluminum oxide barrier
Muftah Al-Mahdawi, Masashi Sahashi
We report on the observation of anisotropic magnetoresistance (AMR) in vertical asymmetric nano-contacts (NCs) made through AlO nano-oxide layer (NOL) formed by ion-assisted ox…
