← ScienceWhich consequence results when applying reverse bias in spin-polarized tunnel junction devices?
A)Increased tunneling magnetoresistance
B)Reduced tunneling magnetoresistance✓
C)Enhanced Coulomb blockade effect
D)Suppressed ferromagnetic resonance damping
💡 Explanation
Applying reverse bias weakens spin-polarized alignment, therefore DECREASING the tunneling magnetoresistance because spin-flip scattering dominates over coherent tunneling, rather than enhancing it under forward bias with constructive interference from aligned spins.
