Evidence of pure spin current
Weiwei Lin, C. L. Chien
Evidences of pure spin current are indistinguishable from those of many parasitic effects. Proper choices of materials and methods are essential for exploring pure spin current phe…
Electrical Detection of Spin Backflow from an Antiferromagnetic Insulator/Y3Fe5O12 Interface
Weiwei Lin, C. L. Chien
Spin Hall magnetoresistance (SMR) has been observed in Pt/NiO/Y3Fe5O12 (YIG) heterostructures with characteristics very different from those in Pt/YIG. We show that the SMR in Pt/N…
Temperature Dependence of Angular Momentum Transport Across Interfaces
Kai Chen, Weiwei Lin, C. L. Chien +1
Angular momentum transport in magnetic multilayered structures plays a central role in spintronic physics and devices. The angular momentum currents or spin currents are carried by…
Enhancement of Thermally Injected Spin Current through an Antiferromagnetic Insulator
Weiwei Lin, Kai Chen, Shufeng Zhang +1
We report large enhancement of thermally injected spin current in normal metal (NM)/antiferromagnet(AF)/yttrium iron garnet(YIG), where a thin AF insulating layer of NiO or CoO can…
Universal domain wall dynamics under electric field in Ta/CoFeB/MgO devices with perpendicular anisotropy
Weiwei Lin, Nicolas Vernier, Guillaume Agnus +5
Electric field effects in ferromagnetic/oxide dielectric structures provide a new route to control domain wall (DW) dynamics with low power dissipation. However, electric field eff…
Effect of Spin Accumulation at Co/Pt Interfaces on Anomalous Hall Effect in Pt/Co/Pt Trilayers
Peng Zhang, Weiwei Lin, Kaixuan Xie +2
As current flows through a Pt/Co/Pt trilayer, spin Hall effect induced by charge current in the Pt layer leads to spin accumulation at the Co/Pt interfaces. Our experiment and calc…
Interfacial charge accumulation effect on magnetic domain wall nucleation and propagation in a Pt/Co/Pt/Al2O3 structure
Weiwei Lin, Nicolas Vernier, Guillaume Agnus +3
We report direct observation of charge accumulation effect on magnetization reversal in a Pt/Co(0.5 nm)/Pt(0.5 nm)/Al2O3 structure with perpendicular anisotropy. By imaging magneti…
Giant thermoelectric effect in Al2O3 magnetic tunnel junctions
Weiwei Lin, Michel Hehn, Laurent Chaput +4
Thermoelectric effects in magnetic nanostructures and the so-called spin caloritronics are attracting much interest. Indeed it provides a new way to control and manipulate spin cur…
Asymmetric magnetization splitting in diamond domain structure: Dependence on exchange interaction and anisotropy
Kaixuan Xie, Xiaopu Zhang, Weiwei Lin +2
The distributions of magnetization orientation for both Landau and diamond domain structures in nano-rectangles have been investigated by micromagnetic simulation with various exch…
A Novel Temperature-Induced Magnetization Transition in Pt/Co/Pt Sandwiches
Weiwei Lin, Hai Sang
It is found in the Pt/Co/Pt(111) sandwiches that perpendicular magnetic anisotropy weakens associated with the dramatic magnetization enhancement as the temperature decreases below…
