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…
Lateral ferromagnetic domain control in Cr2O3/Pt/Co positive exchange bias system
T. Nozaki, M. Al-Mahdawi, S. P. Pati +2
We investigated the perpendicular exchange bias (PEB) switching from negative- to positive-exchange bias state for Cr2O3/Pt/Co exchange coupling thin film system exhibiting positiv…
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…
Magnetoelectric properties of 500 nm Cr2O3 films
P. Borisov, T. Ashida, T. Nozaki +2
The linear magnetoelectric effect was measured in 500 nm Cr2O3 films grown by rf sputtering on Al2O3 substrates between top and bottom thin film Pt electrodes. Magnetoelectric susc…
Chemical analysis of ligand-free silicon nanocrystal surfaces by surface enhanced Raman spectroscopy
İlker Doğan, Ryan Gresback, Tomohiro Nozaki +1
Surface enhanced Raman spectroscopy (SERS) was used to probe the surface chemistry of chlorine-terminated silicon nanocrystal (Si-NC) surfaces in an air-free environment. SERS effe…
