PostDoc in Probing the Magnetic Textures and Spin-Wave Properties of 2D Magnets using NV Magnetometry

Delft University of Technology



The Faculty of Applied Sciences is the largest faculty of TU Delft, with around 550 scientists, a support staff of 250 and 1,800 students. The faculty conducts fundamental, application-oriented research and offers scientific education at the bachelor, master and doctoral levels. The faculty is active in the fields of Life and Health Science & Technology, Nanoscience, Chemical Engineering, Radiation Science & Technology, and Applied Physics.

The Kavli Institute of Nanoscience Delft is a quality-driven, intellectually stimulating institute with a broad scope of research in nanoscience and nanotechnology. The emphasis in our research, which ranges from single-molecule biophysics to quantum information processing of nanoscale devices, is on novel concepts and fundamental breakthroughs. The Institute has state-of-the-art general facilities, most notably for nanofabrication in the Kavli Nanolab Delft. The Kavli Institute of Nanoscience consists of two departments, both also part of the Faculty of Applied Sciences at Delft University of Technology: The Department of Quantum Nanoscience, and the Department of Bionanoscience. 

The van der Sar Lab is part of the department of Quantum Nanoscience at the Kavli Institute of Nanoscience at Delft University of Technology. Delft is a university town close to the larger cities of The Hague and Rotterdam (both <15 min. by train) and Amsterdam (~ an hour by train).

Job Description

Research in the van der Sar lab:

Research in the van der Sar Lab focuses on studying condensed-matter physics using nanoscale magnetic sensing. A central role is played by the nitrogen-vacancy (NV) spin in diamond - an atomic-sized magnetic-field sensor controlled using methods from quantum information processing. NV magnetometry is a high-resolution, quantitative magnetic imaging technique that is compatible with a large range of temperatures, providing a platform that is well suited for exploring correlated-spin phenomena such as spin transport in mesoscopic magnets. 

In this project you will study the magnetic textures and spin-wave transport properties of complex-oxide heterostructures and van der Waals magnets. These materials are currently in the research spotlight as they provide promising new systems for developing new nanoscale spin science and technology. To study these systems, you will use a cryogenic, scanning-NV magnetic imaging system that combines techniques from quantum optics and quantum information processing with scanning probe microscopy.

Job Requirements

We are looking for an enthusiastic candidate with a PhD degree in physics. Experience with spin physics, optics, scanning-probe microscopy, and/or cryogenics is desirable, but not required. Most importantly, the candidate should be fascinated by being able to explore fundamental condensed-matter physics using this state-of-the-art measurement technique. Fluency in English is required.

Terms of Employment

TU Delft offers a customisable compensation package, a discount for health insurance and sport memberships, and a monthly work costs contribution. Flexible work schedules can be arranged. An International Children’s Centre offers childcare and an international primary school. Dual Career Services offers support to accompanying partners. Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities.
