Technische Physik

Prof. Rudolf Gross


The research activities of the Walther-Meißner-Institute are focused on low temperature solid-state and condensed matter physics. The research program is devoted to both fundamental and applied research and also addresses materials science, thin film and nanotechnology aspects. With respect to basic research the main focus of the WMI is on

  • superconductivity and superfluidity,
  • magnetism, spin transport, and spin caloritronics,
  • quantum phenomena in mesoscopic systems and nanostructures,
  • and the general properties of metallic systems at low and very low temperatures.

The WMI also conducts applied research in the fields of

  • solid-state quantum information processing systems,
  • superconducting and spintronic devices,
  • oxide electronics,
  • multi-functional and multiferroic materials,
  • and the development of low and ultra low temperature systems and techniques.

With respect to materials science, thin film and nanotechnology the research program is focused on

  • the synthesis of superconducting and magnetic materials,,
  • the single crystal growth of oxide materials,
  • the thin film technology of complex oxide heterostructures including multi-functional and multiferroic material systems,
  • the fabrication of superconducting, magnetic, and hybrid nanostructures,
  • and the growth of self-organized molecular ad-layers.

The WMI also develops and operates systems and techniques for low and ultra-low temperature experiments. A recent development are dry mK-systems that can be operated without liquid helium by using a pulse-tube refrigerator for precooling. Meanwhile, these systems have been successfully commercialized by the company VeriCold Technologies GmbH at Ismaning, Germany, which meanwhile has been acquired by Oxford Instruments. As further typical examples we mention a nuclear demagnetization cryostat for temperature down to below 100µK, or very flexible dilution refrigerator inserts for temperatures down to about 20mK fitting into a 2inch bore. These systems have been engineered and fabricated at the WMI. Within the last years, several dilution refrigerators have been provided to other research groups for various low temperature experiments. The WMI also operates a helium liquifier with a capacity of more than 150.000 liters per year and supplies both Munich universities with liquid helium. To optimize the transfer of liquid helium into transport containers the WMI has developed a pumping system for liquid helium that is commercialized in collaboration with a company.

Engineering Magnetization Dynamics in a Magnetic Insulator

In magnetic resonance, a high frequency magnetic drive field is employed to excite the precessional motion of the magnetization of a magnet. Besides this fundamental excitation, where all spins are precessing in an orchestrated, collective motion, higher order magnetic resonance modes can be excited and investigated using broadband microwave spectroscopy techniques. Furthermore, as these properties rely on the „magnetic“ bandstructure of the material, they can also be tailored using nano-fabrication methods yielding engineered magnetic structures such as waveguides or resonators.

We are looking for a talented master student, who is eager to explore the different possibilities for tailoring the dynamic magnetic properties of yttrium iron garnet (YIG). The goal of your thesis is to design, fabricate and investigate tailored magnetic bandstructures in YIG, in particular also in freely suspended films. The thesis work involves simulation of the (magnetic) structures, advanced nano-patterning, as well as high frequency spectroscopy of the fabricated devices.

Magnetische Quantenoszillationen in dem antiferromagnetischen Supraleiter kappa-(BETS)2FeBr4

One of the challenging goals in modern materials science is the rational design of multifunctional molecular compounds that combine technologically useful features such as electrical conductivity and magnetism. A promising strategy is to create hybrid organic/inorganic crystals comprising two functional sublattices exhibiting distinct properties. Recently, several compounds have been synthesized in which the metallic conductivity is provided by organic layers sandwiched between inorganic layers responsible for magnetic ordering. The goal of the present Master thesis is to inverstigate the interplay between the magnetic and conducting subsystems in the organic superconductor k-(BETS)2FeBr4 in vicinity of the antiferromagnetic quantum phase transition. Quantum oscillations of magnetization and interlayer resistivity in strong magnetic fields will be used to probe the electronic properties of this material.

Techniques: Strong magnetic fields; magnetotransport; magnetic torque; cryogenic (liquid 4He and 3He) techniques.

Physics: Electronic correlations; magnetic quantum oscillations; antiferromagnetism.
