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.
You may send us your application or contact us by phone or e-mail in advance. 


Current Bachelor ThemesDr. Geoffrey Chanda in the NMR-Lab

  • 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. Supported by the HLD team, you will develop and program measurement routines for your experiments.      

Current Master Topics 

  • 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.

Current PhD ProjectsPhD students Kathrin Götze and Richard Zahn conduct research on current topics in solid state physics

  • Investigation of strongly correlated electron systems by quantum-oscillation 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 (ilya.sheikin@lncmi.cnrs.fr) and Prof. J. Wosnitza from HLD, HZDR, Dresden, Germany (j.wosnitza@hzdr.de).

  • Transport and magnetization of novel metallic materials
    This work aims at the characterization of novel metallic materials by means of electrical transport and magnetization measurements. Experiments will be performed at extreme sample conditions in order to map the entire B-T-phase diagram. Performing high-resolution transport (Shubnikov-de Haas effect) and magnetization (de Haas-van Alphen effect) quantum-oscillation experiments will allow for determining the electronic band structure of single-crystalline novel metalls. In this work, both superconducting and pulsed high-field magnets will be utilized.
