Abstract:
The main objective of our project is to develop a complex multiscale theoretical and experimental framework aimed identify the critical parameters and underlying physical mechanisms of the enhanced energetic efficiency skyrmion manipulation by electric field and spin currents in storage, synaptic and Qubit spintronic devices. Following the complex material issues, pointed out in the literature, we aim to investigate multilayer structures composed by a broad area of spintronic materials among the following classes: simple or complex metallic alloys, functional oxides (multiferroics), rare-earth based oxidic or non-oxidic structures. The main objective will be achieved following specific objectives: (O1) Theoretical predictive analysis of materials and multilayered architectures for PMA, DMI, Rashba intrinsic field anatomy, magnitude and voltage variation for skyrmionic applications controlled by electric field and spin-transfer-torque. (O2) Design of innovative experiments and spintronic devices architectures. (O3) Development of atomistic/micromagnetic models/simulations of the functional response and operating phase diagrams of realistic skyrmionic devices. (O4) Experimental realization and characterization of materials, nanostructures and voltage and spin-transfer torque controlled skyrmionic devices, for correlation with (feedback to) theory. (O5) Theoretical development and design of next generation information manipulation devices.

Abstract:
The main objective of the project consists on the study and the elaboration of new generation spintronic devices with applications in sensor/data storage technologies, whose operation is based on innovative low consumption magnetization manipulation. Its attaining implicates a deep understanding of the underlying physics related to magnetism, spin and charge transport in multilayered thin film mesoscopic structures constituted by complex materials with tailored functional properties. Moreover, delicate technological issues have to be precisely mastered: multistep lithography patterning of spintronic pillar devices with electronic transport perpendicular to the layer’s plane and lateral sizes within the nanometric to micrometric range. The elementary brick of the targeted sensor is the MTJ, based on thin films materials with tailored functional properties. The manipulation of the MTJ magnetization is scheduled to be performed following two mechanisms: (1) the voltage-controlled electric field (E-field) effect on anisotropy and (2) the spin-transfer torque (STT) effect induced by spin-polarized current. While the STT mechanisms have been widely studied in the last decade and already led to novel generation of nonvolatile magnetic random access memories (STT-MRAM), from fundamental point of view, our study surveys the E-field magnetization manipulation. Therefore, we aim to shed light on the complex charge-driven mechanism underlying the E-field control of the PMA. This represents a particularly difficult problematics, especially when dealing with complex magnetic alloy materials with tunable spin polarization and Gilbert damping in epitaxial MTJ multilayer stacks where the electronic transport is controlled by Bloch symmetry filtering effects. The project concluding objective is oriented towards technological transfer targeting a new generation device: elementary cell of a non-volatile data storage matrix with low power consumption information manipulation capacity.

Abstract:
This project addresses innovative fundamental physics of spin and charge transport in Magnetic Tunnel Junctions (MTJ) employing half-metallic ferromagnetic (FM) electrodes with low Gilbert damping and tailor their magneto-transport properties and application potential. The dependence of magnetic anisotropy on the film thickness, composition and interface symmetries will be investigated, aiming towards perpendicular magnetic anisotropy (PMA). Specific MTJ architectures with engineered characteristics, patterned in micrometric and nanometric size pillars, will be elaborated using interface chemical tuning and inserting symmetry dependent quantum wells. They will be characterized by local near field techniques and by temperature and field-dependent tunneling spectroscopy. We focus on understanding the depolarizing mechanisms, lose and recovery of half-metallicity by symmetry filtering effects. The transport mechanisms will be analyzed from correlated static DC and dynamic (noise) transport spectroscopy in variable temperature. The spin torque related noise enhancement in low Gilbert damping FM electrodes based MTJs will be addressed. The influence of electronic structure and magnetism of interfaces on spin and charge transport, the interplay between spin-orbit coupling, PMA, and anisotropic tunneling magnetoresistive effects will be investigated. The experimental studies will be accompanied by theoretical modeling by combining ab-initio, analytical and numerical approaches.
