Lecture 2:

Shaping the future of materials research with machine learning and Big Data

Recent developments in machine learning have brought the expectation that artificial intelligence systems will be ubiquitous in the near future, with large impact on science and technology. The ways researchers develop and optimize materials for varied applications are already affected by the availability of large databases of materials properties and Big Data methodologies [1]. In this lecture, examples will be given of computational methods to handle large amounts of data in sensing and biosensing, which include machine learning techniques to relate impedance spectroscopy data from an electronic tongue to the human perception of taste. For clinical diagnostics, it will be made clear that a convergence of nanotechnology and Big Data resources is required for creating computer-aided diagnosis systems [2]. On one hand, optimized sensors and biosensors need to be produced with nanomaterials and nanotech-related techniques [3], while on the other hand robust computational methods are crucial for distinguishing among very similar responses, as in detection of cancer biomarkers [4]. Most significantly, the shift in paradigms for performing research demands urgent changes in the training of materials researchers.

Lecture 3:

Topological Materials and their potential for applications (from Topological Insulators to Magnetic Skyrmions)

New materials and new phenomena have recently emerged from the interplay between spin-orbit coupling (SOC) and topology effects [1]. The electron states at surfaces or interfaces of topological insulators and also at Rashba interfaces, are characterized by a locking between spin and momentum that can be exploited for an efficient conversion from charge to spin (or spin to charge) currents in spintronic devices. As well, SOC and inversion symmetry breaking by interfaces induce chiral spin interactions that can be used to generate topological protected magnetic solitons called skyrmions. The talk will focus on topological insulators, Rashba interfaces, skyrmions in magnetic multilayers and the resulting perspectives of applications.

  1. I will present experimental results [2] on the conversion between charge and spin currents (at room temperature) by topological insulators (alpha-Sn) or Rashba interfaces (Bi/Ag, LAO/STO) and I will put forward the potential of these conversions for spintronic devices such as magnetic memories or spin-Seebeck heat-electricity converters.
  2. In the second part of the talk [3], I will focus on the room temperature properties of small skyrmions induced by interfacial chiral interaction in magnetic multilayers and describe more particularly the current-induced motion of skyrmions. I will finally discuss the next problems to solve on the route to applications.
