Doctoral candidate specializing in electrical engineering or physics for quantum-based measurements of nanomagnetic field distributions (22-293-2) Monday, 27. June 2022

The Physikalisch-Technische Bundesanstalt (PTB) is the national metrology institute of the Federal Republic of Germany with scientific and technical service tasks. It furthers progress and reliability in metrology for society, the economy and science.

With a starting date as soon as possible, Department 2.5, Semiconductor Physics and Magnetism, is looking for a candidate to fill the following position at our Braunschweig site for a duration of three years:

Doctoral candidate specializing in
electrical engineering or physics for
quantum-based measurements of nanomagnetic field distributions

Remuneration Group 13 TVöD Bund (85 %) ○ fixed-term contract

PTB’s Nanomagnetism Working Group (Working Group 2.52) develops measurement methods for the quantitative characterization of nanomagnetic systems. Based on the established quantitative magnetic force microscopy (qMFM), the spectrum of methods will now be extended by the quantum-based measurement method of scanning NV magnetometry.


Your tasks:

NV centers in diamond allow quantum-based magnetic field measurements with µT resolution. For the quantitative measurement of the field distribution of magnetic systems on the nanometer scale, PTB has recently acquired a scanning NV magnetometer. Within the scope of your doctoral thesis, it has to be calibrated, validated and used to analyze complex spin structures, such as skyrmions. The work is part of the DFG Cluster of Excellence QuantumFrontiers and the DFG Priority Program on Skyrmionics.

Your work will focus on:

  • The realization of quantum-based magnetic field measurements to investigate the nanometer scale spin structure of modern magnetic thin film materials, e.g., skyrmions; for this task, a commercial state-of-the-art scanning NV magnetometer is available
  • Developing and testing concepts for the calibration of nanometer scale magnetic field measurements traceable to SI standards with the aid of nanostructured reference samples manufactured in PTB’s clean room center; based on this work, the achievable field and spatial resolution and the measurement uncertainty are analyzed
  • The analysis of measurement results using analysis and simulation software
  • Writing scientific publications and presenting the results at international congresses
  • Writing project reports and the documentation of the results


Your profile:

  • You have completed your university studies (Master’s or German Diplom) in physics, electrical engineering or a comparable field and have obtained a grade that is “good” or better
  • Ideally, you have knowledge of or practical experience in one of the following fields: solid-state physics, scanning probe microscopy, nanomagnetism, optically detected magnetic resonance or clean room technology
  • You are a strong team player with excellent communication skills
  • You are able to work independently
  • You have a very good command of both spoken and written German and English
  • You are willing to travel within Germany as well as abroad within the scope of your assignment
  • You must have the physical aptitude to work in a laboratory and in a clean room



We offer:

  • A position at one of the world’s leading research institutions with an excellent infrastructure
  • Intensive PhD supervision in an interdisciplinary team
  • Remuneration in accordance with the Collective Bargaining Agreement for the Public Service covering federal employees (Tarifvertrag öffentlicher Dienst Bund – TVöD)
  • Various workplace health and wellness options
  • Good transport connections (bus and bike); a subsidy towards the cost of your public transport ticket for the Braunschweig Region (Job-Abo); free parking
