Bachelor, Master and PhD theses
The HLD offers the possibility for Bachelor, Master, Diploma and PhD theses for interested students of appropriate branches of study. Furthermore, we provide the opportunity to work as a student research assistant at our institute.

Magnetization studies of novel magnetic materials
Novel magnetic materials will be investigated by means of SQUID or vibrating-sample magnetometry. You will use advanced measurement techniques and devices in order to study novel magnetic compounds at extreme sample conditions. You will perform the experiments by use of computer-assisted data acquisition and analyse your data by means of modern software tools.
- Electronical and thermodynamic transport
In this project, you will perform measurements of the electronical and thermodynamical transport. These experiments will be conducted at extreme sample conditions (low temperatures, high magnetic fields, high pressures).
- Thermometry at extreme sample conditions
Precise thermometry at very low temperatures and high magnetic fields is an ambitious task. It needs to be attuned to experimental measurement techniques. There are several methods at choice, e.g. resistance, permeability, permittivity, Coulomb blockade or nuclear spin resonance thermometry. In your bachelor work, you will address one of these techniques in experiment and its underlying theoretical concept.
The student will be supported by the HLD team.
Thermodynamics of spin-ice compounds
Investigation of the magnetic ground state of spin-ice compounds by means of heat-capacity measurements at very low temperatures. You will perform thermodynamic measurements by using the ultralow-temperature equipment of the HLD. Magnetic fields applied to the sample will be produced in superconducting magnets.
Quantum oscillation measurements in strongly correlated electron systems
You will utilize high magnetic fields in order to observe quantum oscillations by means of high resolution transport (Shubnikov- de Haas effect) or magnetization (de Haas-van Alphen effect) measurements. Your data will give insight into the band structure and Fermi surface of novel, not yet understood materials.
- Nuclear magnetic resonance measurements
Investigations of superconducting and magnetic materials by means of nuclear magnetic resonance measurements.
The PhD project is dedicated to quantum-oscillation studies of strongly correlated electron systems in high magnetic fields. Such measurements are the tool-of-choice for the determination of the Fermi-surface topology in metals. In strongly correlated electron systems, high magnetic fields are usually required to observe quantum oscillations. In addition, high magnetic fields often induce electronic phase transitions. Theoretically, such phase transitions are often accompanied by a Fermi-surface reconstruction. This is one of the key questions that will be addressed experimentally within this PhD project. The student will have a unique opportunity to use state-of-the-art high-field facilities of the European Magnetic Field Laboratory. This includes static fields to 36 T and beyond available in Grenoble and Nijmegen, pulsed fields to 90 T and beyond at Dresden as well as low-temperature equipment for sample cooling. This PhD project is part of a larger French-German collaboration. The student will cooperate with theoreticians who will provide band-structure calculations to be compared with the experiment.
The thesis will be financed by the joint French-German ANR-DFG grant “FermiNESt”. The PhD student will be jointly supervised by Dr. I. Sheikin from LNCMI, CNRS, Grenoble, France (firstname.lastname@example.org) and Prof. J. Wosnitza from HLD, HZDR, Dresden, Germany (email@example.com).
