Subject: Postdoctoral position: Ab-initio calculation of the electronic str= ucture near interfaces in magnetic tunnel junctions

Category: Job

Message:

A 12 month post doctoral position is available at the CNRS institute CEM= ES (Center for Material Elaboration and Structural Studies) in Toulouse, Fr= ance. This one year position is funded by the French national agency for re= search (ANR) and can start from autumn 2008 or begining 2009. It is part of= the ANR project “SPINCHAT” (Spin and Charge Transfer in single= crystal magnetic tunnel junctions) involving three research groups from Na= ncy (LPM), Grenoble (CEA-SPINTEC) and Toulouse (CEMES-CNRS).

The Postdoctoral position proposed at the CEMES will consist in calculating= the electronic structure of magnetic tunnel junctions using DFT-based firs= t principles methods. The calculations will be done with the LAPW code Wien= 2k and with the multiple scattering code Layer-KKR. The single crystal magn= etic tunnel junctions which will be studied consist in a MgO insulating bar= rier sandwiched between magnetic electrodes made with bcc Fe or with a bcc Fe= xCo1-x alloy. We wish to understand how the electronic str= ucture changes near the barrier/electrode interfaces, when the electrode al= loy composition and the interface atomic structure are modified. In particu= lar, we will study the possible interface states or resonances, as well as = the possible quantum well states which could appear when a thin layer is in= serted between the barrier and one of the electrodes. These calculations of= the electronic structure will be very useful to understand the spin depend= ent transport properties of the junction. They also will permit to calculat= e the electron energy loss spectra (EELS) at the Fe/MgO interfaces that wil= l be compared to experimental spectra measured in (S)TEM experiments.

As an applicant, you must have a PhD in Solid State Physics or in Material = Science. You must have a good experience in electronic structure calculatio= n (DFT-based codes). Experience on magnetic materials will also be apprecia= ted.
