Objectives

The main objective of this Project is the computational design of high-performance functional MFTJs by interface engineering. For the practical evaluation of a large variety of model heterostructures we shall consider a set of performance criteria, including FE polarization stability, values of magnetic moments and TER ratio, and the strength of the coupling between polarization and magnetization.

To ensure the handles required to reach the main objective, several specific objectives have to be accomplished, as follows:

O1. To determine the configurations of the most performant, ideal MFTJs models (without interface defects).
O2. To bring relevant information on the effects of defects at interfaces on the performance of the MFTJs.
O3. To bring relevant information on the effect of strain on the MFTJs performance.
O4. To make a significant progress in tailoring the interface region in the presence of defects and strain, towards the realization of various electronic device architectures.
