Magnetic Materials
Magnetic and highly correlated electron systems are important research themes at HZB. Besides a range of laboratory techniques we exploit the unique aspects of the synchrotron radiation source BESSY II and the neutron source BER II to investigate problems of basic and applied research. Quantum and frustrated magnetism, transition metal oxides, superconductivity, and magnetic nanostructures and interfaces are key topics of general importance in which photon and neutron based methods make a particularly high impact. The overall aim is to form the scientific capabilities to address the challenges of the development of new magnetic materials and devices. Maximum insight into complex behavior can be gained using a combination of techniques, with special emphasis on sophisticated sample environments and extreme conditions, especially high magnetic fields and low temperatures.
In house research is carried out by a number of units within the division Magnetic Materials which work together closely on joint projects. The Institute for Complex Magnetic Materials specializes in soft and hard x-ray diffraction in combination with neutron diffraction, small angle and reflectivity techniques, and magnetism under extreme conditions. Presently, it coordinates the Helmholtz Virtual Institute New states of matter and their excitations. The Department for Magnetization Dynamics focuses on angle resolved photoemission and photoelectron emission microscopy. The Department for Quantum Phenomena in Novel Materials specializes in magnetic structure determination and inelastic neutron scattering as well as operating a crystal growth laboratory. Detailed information on structure-property relations of materials for energy conversion and of geomaterials (magnetic minerals) are obtained in the Department for Crystallography. In addition, the division Magnetic Materials is responsible for the development of a High Field Magnet for neutron scattering and a Vector Magnet for BESSY II.
