Tunneling magnetoresistance of Fe/ZnSe (001) single- and double-barrier junctions as a function of interface structure

J. Peralta-Ramos, A. M. Llois

In this contribution, we calculate the spin-dependent ballistic and coherent transport through epitaxial Fe/ZnSe (001) simple and double magnetic tunnel junctions with two differen…

Tunnel transport through multiple junctions

J. Peralta-Ramos, A. M. Llois

We calculate the conductance through double junctions of the type M(inf.)-Sn-Mm-Sn-M(inf.) and triple junctions of the type M(inf.)-Sn-Mm-Sn-Mm-Sn-M(inf.), where M(inf.) are semi-i…

Tunnelling through a semiconducting spacer: complex band predictions vs. thin film calculations

J. Peralta-Ramos, J. Milano, A. M. Llois

Using a simple tight-binding model, we compare the limitations of the tunnelling predictions coming out of the complex band structure of a semiconductor with the output of thin fil…

Gate control of the tunneling magnetoresistance in double-barrier junctions

J. Peralta-Ramos, A. M. Llois

We calculate the conductances and the tunneling magnetoresistance (TMR) of double magnetic tunnel junctions, taking as a model example junctions composed of Fe/ZnSe/Fe/ZnSe/Fe (001…

Transmission spectra of Fe/MgO (001) double-barrier tunnel junctions at finite bias

J. Peralta-Ramos, A. M. Llois

In this contribution, we calculate in a self-consistent way the ballistic transmission as a function of energy of one Fe/MgO (001) single-barrier and one double-barrier tunnel junc…
