Hello

How to find the Tunnel Magneto Resistance at 0 bias voltage, since the current at zero bias are 0A


Thanks&Regards

See http://docs.quantumwise.com/tutorials/fe_mgo_fe/fe_mgo_fe.html
The TMR can be defined via the conductance which is well-defined also at zero bias.

Yes, it does give the TMR value at zero bias in terms of conductance calculated for parallel and anti-parallel magnetization configurations of the ferromagnetic electrodes.
