Dr. Ralf Feyerherm

Staff scientist at the department "Quantum Phenomena in Novel Materials".

Current research interest: X-ray diffraction and resonant magnetic scattering studies of highly correlated oxides and intermetallics.

Scientific career: I studied physics at the Technical University Braunschweig, Germany, specializing on experimental solid state physics using nuclear probes. In my diploma work I used Mössbauer spectroscopy to study the vibrational dynamics of polymers. I received my Diplom (masters degree) in 1991. In the same year, I started my Ph.D. work at the ETH Zürich and at the Paul-Scherrer-Institute (PSI), Switzerland. I received my Ph.D. degree in 1995 with muon-spin rotation studies on heavy-electron superconductors. For my postdoc time (1996/1997) at McMaster University, Canada, I again switched the technique, now using neutron diffraction to study magnetic intermetallic compounds. Back to Germany in 1997, I joined the Hahn-Meitner-Institute, now Helmholtz Zentrum Berlin. My first research focus was neutron diffraction on molecule-based magnetic materials. Since the year 2000, I was engaged in the construction of the synchrotron beamline MAGS for high-resolution diffraction and x-ray resonant magnetic scattering (XRMS) at BESSY. Between 2005 and 2013, this beamline has been in user operation and we have performed several successful XRMS experiments on multiferroic rare-earth manganites.
