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…
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…
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…
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…
