Growth-dependent Interlayer Chiral Exchange and Field-free Switching
Yu-Hao Huang, Chao-Chung Huang, Wei-Bang Liao +2
Interfacial Dzyaloshinskii-Moriya interaction (DMI) has long been observed in normal metal/ferromagnetic multilayers, enabling the formation of chiral domain walls, skyrmions and o…
Efficient Spin-Orbit Torque Switching with Non-Epitaxial Chalcogenide Heterostructures
Tian-Yue Chen, Cheng-Wei Peng, Tsung-Yu Tsai +4
The spin-orbit torques (SOTs) generated from topological insulators (TIs) have gained increasing attention in recent years. These TIs, which are typically formed by epitaxially gro…
Current-Induced magnetization switching by the high spin Hall conductivity -W
Wei-Bang Liao, Tian-Yue Chen, Yari Ferrante +2
The spin Hall effect originating from 5d heavy transition metal thin films such as Pt, Ta, and W is able to generate efficient spin-orbit torques that can switch adjacent magnetic…
Spin-orbit torques acting upon a perpendicularly-magnetized Py layer
Tian-Yue Chen, Yongxi Ou, Tsung-Yu Tsai +2
We show that Py, a commonly-used soft ferromagnetic material with weak anisotropy, can become perpendicularly-magnetized while depositing on Ta buffer layer with Hf or Zr insertion…
The current-induced spin-orbit torque and field-free switching from Mo-based magnetic heterostructures
Tian-Yue Chen, Hsin-I Chan, Wei-Bang Liao +1
Magnetic heterostructure Mo/CoFeB/MgO has strong perpendicular magnetic anisotropy and thermal stability. Through current-induced hysteresis loop shift measurements, we show that t…
A Comparative Study on Spin-Orbit Torque Efficiencies from W/ferromagnetic and W/ferrimagnetic Heterostructures
Ting-Chien Wang, Tian-Yue Chen, Chun-Te Wu +2
It has been shown that W in its resistive form possesses the largest spin-Hall ratio among all heavy transition metals, which makes it a good candidate for generating efficient dam…
Spin-orbit torque magnetometry by wide-field magneto-optical Kerr effect
Tsung-Yu Tsai, Tian-Yue Chen, Chun-Ting Wu +2
Magneto-optical Kerr effect (MOKE) is an efficient approach to probe surface magnetization in thin film samples. Here we present a wide-field MOKE technique that adopts a Khler…
Tunable Spin-Orbit Torques in Cu-Ta Binary Alloy Heterostructures
Tian-Yue Chen, Chun-Te Wu, Hung-Wei Yen +1
The spin Hall effect (SHE) is found to be strong in heavy transition metals (HM), such as Ta and W, in their amorphous and/or high resistivity form. In this work, we show that by e…
The Spin-Orbit Torque from a Magnetic Heterostructure with High-Entropy Alloy
Tian-Yue Chen, Tsao-Chi Chuang, Ssu-Yen Huang +2
High-entropy alloy (HEA) is a family of metallic materials with nearly equal partitions of five or more metals, which might possess mechanical and transport properties that are dif…
