Remote | Physics Expert (Condensed Matter / Magnetic Materials) — $80–$160/hour

We are sharing a specialised consulting opportunity for experienced Physics Experts in condensed matter physics and magnetic materials with strong expertise in magnetic structure factors, propagation-vector analysis, magnetic space groups, neutron scattering, BNS notation, AFM/FM phase classification, birefringence, and magneto-optic phenomena.

Selected professionals will contribute to a research-level physics project focused on magnetic ordering, magnetic symmetry, neutron-diffraction interpretation, and the relationship between experimentally observed signatures and underlying magnetic structure. The work requires strong theoretical and experimental judgement, careful symmetry analysis, and the ability to communicate technical conclusions clearly. No prior experience in AI is required.

Birefringence & Magneto-Optic Effects

• Evaluate birefringence signatures associated with magnetic ordering
• Analyse magneto-optic Kerr effect behaviour in selected materials
• Connect optical responses to symmetry and magnetic structure
• Distinguish magnetic from non-magnetic contributions where relevant
• Interpret experimental signatures in terms of underlying physical mechanisms

Research-Level Evaluation

• Review theoretical and experimental analyses for accuracy and consistency
• Identify weaknesses in symmetry assignments or magnetic interpretations
• Provide detailed written feedback and technical rationale
• Compare alternative magnetic-structure models where appropriate
• Support rigorous evaluation of research-level condensed matter problems

Ideal Profile

• Strong expertise in magnetic structure factor calculations
• Demonstrated experience with propagation-vector analysis
• Practical knowledge of magnetic symmetry and phase identification
• Direct experience classifying magnetic space groups
• Familiarity with MAGNDATA
• Strong working knowledge of BNS notation
• Experience with neutron scattering or neutron diffraction
• Strong understanding of antiferromagnetic and ferromagnetic ordering

• Ability to provide precise, defensible technical feedback
• No prior AI-training or model-evaluation experience is required

Engagement Details

• Independent contractor engagement
• Fully remote
• Compensation: $80–$160/hour
• Work will involve magnetic structure factor calculations, propagation-vector analysis, magnetic space group identification, AFM/FM phase classification, neutron scattering, BNS notation, MAGNDATA, birefringence, and MOKE interpretation
• Strong condensed matter and magnetic-materials expertise is central to this engagement
• Assignments may involve theoretical magnetic structures, neutron-diffraction data, symmetry classifications, optical signatures, and research-level technical evaluation
• Project scope, workload, material systems, and evaluation standards may evolve depending on project requirements
• Work must be completed without using confidential or proprietary information belonging to any employer, research institution, laboratory, collaborator, or other third party
