Bio:

Dr.-Ing. Alex Aubert completed his PhD in the Department of Magnetic Materials for Energy at the SATIE CNRS laboratory in France. His doctoral research focused on unraveling the physics underlying magnetoelectric composites, including AC and DC magnetostriction and magnetic anisotropy, to optimize the magnetoelectric effect. These insights led to the development and testing of a magnetic sensor for electrical engineering applications.

In 2018, he joined BCMaterials (Leioa, Spain) as a postdoctoral fellow, contributing to the European H2020 NOVAMAG project on new permanent magnets. He took part in the fabrication and understanding of the hard magnetic properties of intermetallics ThMn12-based nitrides.

Since 2019, Dr.-Ing. Aubert has been part of the Functional Materials group led by Prof. Gutfleisch. His primary focus has been the development of advanced experimental setups for functional magnetic materials. He contributed significantly in designing and constructing ULMAG (ULtimate MAGnetic characterization), a unique and versatile system capable of simultaneously measuring element-selective X-ray magnetic circular dichroism (XMCD) in combination with X-ray diffraction and bulk magnetic properties, such as magnetization, magnetostriction, magnetoresistance, and magnetocaloric effects. This system was successfully implemented at the ID12 beamline of the ESRF (France).

Building on this work, Dr.-Ing. Aubert is now involved in the PUMA project, which aims to implement a 50T pulsed magnetic field at the ID32 beamline of the ESRF. This ambitious project seeks to enable simultaneous measurements of macroscopic properties and XMCD in the soft X-ray regime.

In addition to his expertise in experimental setups, Dr. Aubert has been actively involved in the development of both rare-earth-based and rare-earth-free permanent magnets, as well as magnetocaloric 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.
