Universities and Institutes of France

August 15, 2022

Description

  • Organisation/Company: CNRS
  • Research Field: Physics
  • Researcher Profile: First Stage Researcher (R1)
  • Application Deadline: 15/08/2022 23:59 - Europe/Brussels
  • Location: France › RENNES
  • Type Of Contract: Temporary
  • Job Status: Full-time
  • Hours Per Week: 35
  • Offer Starting Date: 01/10/2022
  • The PhD student will primarily work at IPR (unité mixte de Recherche CNRS UMR 6251 at Université Rennes 1) where he will conduct ultrafast laser experiments devoted to Brillouin scattering. In view of the highly collaborative component of this project, the student will work closely with all of the team members from the consortium (LP2N Bordeaux, UMPhy Massy, Lab- STICC Brest). The student will spend time abroad at the collaborators institutions in order to perform joint measurements campaigns.

    The characteristic frequencies of phonons and magnons span from tens of GHz up to the THz range. Spectroscopy in this context remains limited to time-domain Brillouin scattering also referred to as coherent Brillouin scattering hence in a systematic out-of-resonance regime. The main goal of the PhD project is to develop and utilize an instrument implementing a novel spectroscopy approach that relies on tunable optical resonant excitation where the pulsed laser repetition-rate can be continuously varied to match any magnonic or phononic eigen-frequencies of the material under investigation. The setup and the extended capacities of this novel method will be demonstrated by exploring the magnetic and acoustic properties of a chosen set of specific materials. The student will be in charge of the development of femtosecond high-repetition rate measurements, data acquisition and analysis, as well as theoretical modeling.

    Additional comments

    The candidate should hold a Master diploma in the following fields, optics, acoustics or mechanics. Background in experimental optics with femtosecond lasers, acoustics or spintronics is very welcome. The candidate should speak English decently in order to exchange with the non-French speaking team members.
