Shot noise in magnetic tunnel junctions from first principles
Kai Liu, Ke Xia, Gerrit E. W. Bauer
We compute the shot noise in ballistic and disordered Fe/MgO/Fe tunnel junctions by a wave function-matching method. For tunnel barriers with no more than 5 atomic layers we find a…
Angular momentum transfer torques in spin valves with perpendicular magnetization
Xingtao Jia, Ying Li, Ke Xia +1
Spin valves incorporating perpendicularly magnetized materials are promising structures for memory elements and high-frequency generators. We report the angular dependence of the s…
Influence of the Surface Structure and Vibration Mode on the Resistivity of Cu Films
Ya-Ni Zhao, Shi-Xian Qu, Ke Xia
The influence of the surface structure and vibration mode on the resistivity of Cu films and the corresponding size effect are investigated. The temperature dependent conductivitie…
Thermal spin-transfer in Fe-MgO-Fe tunnel junctions
Xingtao Jia, Ke Xia, Gerrit E. W. Bauer
We compute thermal spin transfer torques (TST) in Fe-MgO-Fe tunnel junctions using a first principles wave function-matching method. At room temperature, the TST in a junction with…
Nonlinear bias dependence of spin-transfer torque from atomic first principles
Xingtao Jia, Ke Xia, Youqi Ke +1
We report first-principles analysis on the bias dependence of spin-transfer torque (STT) in Fe/MgO/Fe magnetic tunnel junctions. The in-plane STT changes from linear to nonlinear d…
Spin transfer torque on magnetic insulators
Xingtao Jia, Kai Liu, Ke Xia +1
Recent experimental and theoretical studies focus on spin-mediated heat currents at interfaces between normal metals and magnetic insulators. We resolve conflicting estimates for t…
