PhD Position in Research on Magnetic Nanoparticles

Advertising institute: JCNS-1 - Neutron Scattering
Reference number: D132/2017, Physics, chemistry, engineering

The Jülich Centre for Neutron Science (JCNS) operates neutron scattering instruments at world leading neutron sources in Garching (FRM II), Grenoble (ILL) and Oak Ridge (SNS) to make them accessible to external users, and uses them for its own research in magnetism and soft matter. Furthermore, the JCNS is a major contributor to the European Spallation Source (ESS) that is currently being built in Lund, Sweden.

In the frame of a joint Jülich-Garching PhD Program we open a PhD topic “Self-Assembly of Magnetic Dumbbell Nanoparticles Studied by Advanced Scattering Techniques”.

This project deals with studies of magnetic and structural properties of dumbbell nanoparticles. The dumbbell nanoparticles each consist of a noble-metal seed nanoparticle linked to a magnetic nanoparticle. The size and composition of both particles can be varied, giving rise to many applications in targeted drug delivery, solar-power systems and catalysis. The aim of this project is to understand and subsequently control the self-assembly of dumbbell nanoparticles by adjusting the size of both the seed and magnetic nanoparticles, concentration and composition of seed nanoparticles and by exposing them to external magnetic fields.

The particles are being made available through collaborations. The project involves in-house characterization of the samples with scanning electron microscopy (SEM), magnetization measurements (PPMS and MPMS), small-angle x-ray scattering (SAXS) and x-ray diffraction (XRD). Preliminary characterization will be carried out at Forschungszentrum Jülich.

Neutron and synchrotron x-ray scattering experiments will be performed at FRM II in Garching, ILL, DESY, ESRF, as well as at overseas research facilities.

The PhD student will be stationed at FRM II in Garching. Frequent trips to Forschungszentrum Jülich and other research facilities are expected.

Your Job:

  • Perform in-house characterization of samples at FZJ
  • Perform state-of-the-art scattering experiments at FRM-II and at other national and international research facilities
  • Analysis of collected data
  • Interpretation and publication of results in high profile journals
  • Presentation of results at national and international conferences.

Your profile

  • A Master’s degree (or equivalent) in physics, chemistry, engineering or a similar area
  • A strong background in condensed matter physics
  • Self-starter with the ability to work independently and in a team
  • Good level of cooperative and communicative skills
  • Good skills in spoken and written English
  • Experience with scientific programming and data analysis is desirable, but not a prerequisite
  • Experience with scattering methods is a plus, but not a prerequisite.

Our Offer

  • Access to state-of-art large scale facilities around the world
  • Work within a dynamic international team
  • Limited position for 3 years
  • Salary and social benefits in conformity with the provisions of the Collective Agreement for the Civil Service (TVöD)

Forschungszentrum Jülich aims to employ more women in this area and therefore particularly welcomes applications from women.
We also welcome applications from disabled persons.
