PhD Position – Non-collinear Altermagnetic Weyl Semimetal: Polarized Neutron Scattering Investigations

Are you interested in uncovering the physics of altermagnetic Weyl semimetals using polarized inelastic neutron scattering? Then join us now.

The Jülich Centre for Neutron Science – Quantum Materials and Collective Phenomena (JCNS-2) offers an outstanding environment for cutting-edge research in quantum materials, combining internationally renowned expertise in neutron scattering with advanced in-house characterization facilities and access to leading large-scale facilities. Your research will contribute to the emerging field of altermagnetism and the development of future spintronic and quantum technologies with broad societal impact.

Your Job

Momentum-dependent spin splitting is traditionally associated with spin–orbit coupling effects such as Rashba and Dresselhaus interactions. However, recent symmetry analysis reveals that antiferromagnets can exhibit spin splitting even without SOC, including in centrosymmetric, light-element materials—an emerging class known as altermagnets, opening new directions for spintronics.

This PhD project will use polarized inelastic neutron scattering to explore a non-collinear antiferromagnet, aiming to provide definitive evidence of altermagnetism beyond the collinear limit. The work will uncover chiral magnon behavior and push the experimental frontier of altermagnetic research.

Your tasks include:

• Preparation of samples for neutron diffraction experiments
• Characterization using in-house PPMS, MPMS, and X-ray diffraction
• Perform scattering experiments at large-scale neutron and x-ray scattering facilities
• Evaluation, documentation, and publication of the obtained data via reports, manuscripts, and presentations
• Cooperation with and co-supervision of intern and master students

Your Profile

• Master's degree or equivalent in physics, chemistry, materials science, crystallography, or a related field
• Experience in (neutron) scattering techniques is of advantage
• A scientific background in the proposed research area is advantageous but not mandatory
• Very good command of written and spoken English with extensive vocabulary is required (at least B2 level according to the CEFR), ideally supported by a certificate confirming the language level. Knowledge of the German language is not mandatory but certainly appreciated
