Neutron and synchrotron instruments
Reflecting our main research interests in magnetism, our Institute "Quantum Phenomena in Novel Materials" operates the E2, E4, and E5 neutron diffractometers at the BER II reactor, as well as two experimental stations at the synchrotron beamline UE46_PGM-1 at BESSY II.

E2 is a flat-cone diffractometer, specialised on the measurement of weak Bragg reflections or diffuse scattering on single crystals.
E4 is a two-axis diffractometer which is mainly used for determining magnetically ordered structures of single crystals under extreme conditions like high magnetic field or high pressure.
E5 is a four-circle diffractometer which allows detailed investigation of crystal and magnetic structures from single crystal samples, recent examples include the spin structures of YTiO3 and alpha-CaCr2O4.
UE46_PGM-1 is a beamline for resonant magnetic scattering and circular dichroism in the soft-x-ray regime. Here, we operate two experimental stations: the high-field and XUV diffractometers.
