Chirality-Induced Noncollinear Magnetization and Asymmetric Domain-Wall Propagation in Hydrogenated CoPd Thin Films
Wei-Hsiang Wang, Ching-Yang Pan, Chak-Ming Liu +2
Array-patterned CoPd-based heterostructures are created through e-beam lithography and plasma pretreatment that induces oxidation with depth gradient in the CoPd alloy films, break…
Exchange-bias dependent diffusion rate of hydrogen discovered from evolution of hydrogen-induced noncollinear magnetic anisotropy in FePd thin films
Wei-Hsiang Wang, Yu-Song Cheng, Hwo-Shuenn Sheu +2
Hydrogenation-induced noncollinear magnetic anisotropy is observed from the evolution of the magnetic domains in FePd alloy thin films using magneto-optic Kerr effect (MOKE) micros…
Dependence of magnetic domain patterns on plasma-induced differential oxidation of CoPd thin films
Wei-Hsiang Wang, Chak-Ming Liu, Tzu-Hung Chuang +3
We demonstrate the evolution of the micro-patterned magnetic domains in CoPd thin films pretreated with e-beam lithography and O2 plasma. During the days-long oxidation, significan…
Plasma-induced magnetic patterning of FePd thin films without and with exchange bias
Wei-Hsiang Wang, Po-Chun Chang, Pei-hsun Jiang +1
We demonstrate control of magnetic domain structures in continuous FePd thin films by patterning their surfaces with plasma treatment. The Fe-oxide layer formed on the surface upon…
Weak Localization and Weak Antilocalization in Double-Gate a-InGaZnO Thin-Film Transistors
Wei-Hsiang Wang, Elica Heredia, Syue-Ru Lyu +4
We demonstrate manipulation of quantum interference by controlling the competitions between weak localization (WL) and weak antilocalization (WAL) via variation of the gate voltage…
Universal dependence on the channel conductivity of the competing weak localization and antilocalization in amorphous InGaZnO thin-film transistors
Wei-Hsiang Wang, Syue-Ru Lyu, Elica Heredia +4
We investigate the gate-voltage dependence of the magnetoconductivity of several amorphous InGaZnO (a-IGZO) thin-film transistors (TFTs). The magnetoconductivity exhibits gate-…
Competing weak localization and weak antilocalization in amorphous indium-gallium-zinc-oxide thin-film transistors
Wei-Hsiang Wang, Syue-Ru Lyu, Elica Heredia +5
We have investigated the gate-voltage dependence and the temperature dependence of the magnetoconductivity of amorphous indium-gallium-zinc-oxide thin-film transistors. A weak-loca…
