Bio:

Dr.-Ing. Alex Aubert is an electrical engineer from ESME Sudria in Paris (France). He also received a M.Sc. in Physics and Engineering of Energy in 2015 from ENS Paris-Saclay in France. He carried out his PhD in the department of Magnetic Materials for the Energies at SATIE CNRS laboratory (France). His doctoral research focused on better understanding the physics involved in magnetoelectric composites (i.e. magnetostriction, magnetic anisotropy etc) in order to optimize the magnetoelectric effect. Based on these findings, a magnetic sensor was built and tested for electrical engineering applications. After the PhD, he joined BCMaterial (Spain) in 2018 as a postdoctoral fellow to work on new permanent magnets in the European H2020 NOVAMAG project. He took part in the fabrication and understanding of the hard magnetic properties of intermetallics ThMn12-based nitrides. These materials show a great potential to replace the high performance NdFeB-based permanent magnets with less critical (rare-earth) materials.

Since October 2019, he works as postdoctoral fellow in the Functional Materials group of Prof. Gutfleisch. He is currently involved in the BMBF project ULMAG (ULtimate MAGnetic characterization). The aim of this project is to build a unique and versatile experimental set-up to measure under strictly the same experimental conditions element-selective X-ray magnetic circular dichroism (XMCD) in combination with x-ray diffraction and bulk magnetic properties of materials like the magnetocaloric effects, magnetostriction, and magnetoresistance. This experimental setup is planned to be implemented at the beamline ID12 in the European Synchrotron Radiation Facility (ESRF) in Grenoble (France) and will serve as a versatile tool for combined macroscopic and microscopic characterization of magnetic materials.

Skills:

Dr.-Ing. Alex Aubert has experience in interdisciplinary fields of the material science and particularly in functional magnetic materials: sample preparation (polycrystalline ceramics and metallic alloys), structural (X-Ray and Neutron diffraction), microstructural (SEM) and magnetic characterization (PPMS, VSM, SQUID, DC & AC Magnetostriction, Magnetocaloric effect). In addition, his knowledge in electrical engineering is complementary to build new experimental setup for functional materials.
