Full TextAbstract
Abstract Tunneling magnetoresistance (TMR) is studied by using non-equilibrium Green s function method based on a single-band tight-binding approximation in Fe/MgO/Fe junction with random energy (RE) at interfaces. Roughness associated with interdiffused regions at Fe/MgO interfaces are introduced as RE on site elements of interfaces (atoms adjacent to interfaces). Calculations show that TMR and current density decrease in parallel configuration, but current density increases in anti-parallel configuration with roughness.
