Spin- and Symmetry-Filtering Combined Tunnel Magnetoresistance through Epitaxial MgO/EuS Tunnel Barriers
Zhiwei Gao, Yihang Yang, Fen Liu +2
We created epitaxial magnetic tunnel junctions of FeCo/MgO/EuS on MgO buffered Si (100). Tunnel magnetoresistance reached up to 64% at 4.2 K. An unexpected fast drop of magnetoresi…

Resonant TMR inversion in LiF/EuS based spin-filter tunnel junctions
Fen Liu, Yihang Yang, Qian Xue +3
Resonant tunneling can lead to inverse tunnel magnetoresistance when impurity levels rather than direct tunneling dominate the transport process. We fabricated hybrid magnetic tunn…
