Spin-dependent tunneling through double-barrier quantum wells with random corrugation interfacial roughness

► We use the transfer matrix method to study spin-dependent transmission through the NM/EuS/NM/EuS/NM junction which affected by random corrugation interfacial roughness. ► The temperature dependence of spin-splitting energy is calculated for EuS magnetic barrier within the mean-field approximation. ► The effect of random nonplanar interfacial is investigated on transmission for several widths of quantum well at different temperatures. ► Our results show that the scattering process due to random roughness open the new conduction channels (the dip and peak resonance energies).
