Titre : Ultrafast spintronics
Résumé : This PhD work here aims at assessing the potential of new spintronic components at the picosecond timescale. It will tackle three topics. The first one concerns spintronic THz emitters in which spin current bursts will be studied in detail in order to unveil the relevant physical quantities responsible for an efficient THz emission. The second deals with antiferromagnets and their ability to be applied in new ultra-fast spintronic components. These materials will be manipulated using pure spin currents generated by ultra-fast demagnetization of an adjacent ferromagnetic layer. The last topic deals with time-resolved imaging of non-collinear structures subjected to spin current stimuli. Partners involved : SPEC (lead), UMPhy, Soleil.
Titre : topological insulators/magnetic systems for spin-charge conversion
Résumé : The PhD work is on spin to charge current conversion study from a BiSb topological insulator. A large effort will be dedicated to MBE growth aiming at the control of structural and electronic interfacial properties of new TI/Ferromagnetic heterostructures. Three laboratories will be mainly involved in the PhD work addressing this topic. It will involve C2N which has recently started the study of BiSb MBE growth, the researchers from the CASSIOPEE beamline at Synchrotron SOLEIL (Angle-Resolved PhotoEmission Spectroscopy-ARPES) and Spin Angle-Resolved PhotoEmission Spectroscopy -SARPES)) and UMPhy for the magneto-transport and spintronic properties.
