Offer DescriptionIn addition to heavy metals with strong spin-orbit coupling (SOC), some 2D systems have strong conversion rates between charge current and pure spin current. Among these systems are the surfaces or interfaces of topological insulators which are new states of matter. The growth of these materials will allow us to develop new types of magnetic memory and other spintronic devices that will reduce energy consumption as well as new kind of devices to be exploited in spin-caloritronics (harvesting energy).
Within the framework of the ERC CoG MAGNETALLIEN project, we are seeking a highly motivated young student with background in solid state physics. We have a bunch of growth techniques such as Molecular Beam Epitaxy interconnected in ultra-high vacuum including in-situ ARPES characterization. The candidate will be benefit from these facilities, as well as training and access to clean room platform to pattern the devices. The aim of the project is to harness SOC on epitaxial compounds either at interfaces, such as Topological Insulators or Weyl semimetals, or bulk SOC, such as B20 compounds, looking for optimization of spin-charge interconversion towards AC spin pumping detection.
The Institut Jean Lamour (IJL) is a joint research unit of CNRS and Université de Lorraine. Focused on materials and processes science and engineering, it covers: materials, metallurgy, plasmas, surfaces, nanomaterials and electronics. IJL has 263 permanent staff (30 researchers, 134 teacher-researchers, 99 IT-BIATSS) and 394 non-permanent staff (182 doctoral students, 62 post-doctoral students / contractual researchers and more than 150 trainees), of 45 different nationalities.
Partnerships exist with 150 companies and our research groups collaborate with more than 30 countries throughout the world. Its exceptional instrumental platforms are spread over 4 sites; the main one is located on Artem campus in Nancy.This study is part of the ERC CoG MAGNETALLIEN project which aim to probe AC detection of spin pumping signal and its high harmonics. The main tasks of the selected candidate are as follows: Growth of epitaxial compounds such as alpha-Sn, half Heusler topological insulator, and B20 compounds integrated with other layers. Carry out the micro/nano fabrication of devices based on previous systems and perform the electrical and magneto-transport characterizations. Evaluation of the spin-charge current interconversion rates efficiency by DC spin pumping, spin-torque ferromagnetic resonance, second harmonic and/or spin Seebeck effect techniques.RequirementsResearch Field Chemistry Education Level Master Degree or equivalentResearch Field Physics Education Level Master Degree or equivalentResearch Field Technology Education Level Master Degree or equivalentLanguages FRENCH Level BasicResearch Field Chemistry Years of Research Experience NoneResearch Field Physics Years of Research Experience NoneResearch Field Technology Years of Research Experience NoneAdditional InformationAdditional commentsBackground in solid-state physics.
