Journal Article
Spin and valley dependent transport and tunneling magnetoresistance in irradiated ferromagnetic WSe2double barrier junctions
2025
Overview
Spin and valley polarizations (
P
s
and
P
KK’
) and tunneling magnetoresistance (TMR) are demonstrated in the ferromagnetic/barrier/normal/barrier/ferromagnetic WSe
2
junction, with the gate voltage and off-resonant circularly polarized light (CPL) applied to the two barrier regions. The minimum incident energy of non-zero spin- and valley-resolved conductance has been derived, which is consistent with numerical calculations and depends on the electric potential
U
, CPL intensity ΔΩ, exchange field
h
, and magnetization configuration: parallel (P) or antiparallel (AP). For the P (AP) configuration, the energy region with
P
KK’
= -1 or
P
s
= 1 is wider (narrower) and increases with ΔΩ. As
h
increases, the
P
s
= 1 (
P
KK’
= -1 or
P
s
= 1) plateau becomes wider (narrower) for the P (AP) configuration. As
U
increases, the energy region with
P
KK’
= -1 increases first and then moves parallel to the
E
F
-axis, and the energy region with
P
s
= 1 for the P configuration remains unchanged first and then decreases. The energy region for TMR = 1 increases rapidly with
h
, remains unchanged first and then decreases as
U
increases, and has little dependence on ΔΩ. When the helicity of the CPL reverses, the valley polarization will switch. This work sheds light on the design of spin-valley and TMR devices based on ferromagnetic WSe
2
double-barrier junctions.
