Abstract

I visited the ISIS facility at Rutherford Appleton Laboratory, UK, to conduct powder neutron diffraction experiments with a high-resolution long-wavelength time-of-flight (TOF) diffractometer WISH and inelastic neutron scattering experiments with a TOF spectrometer MARI on an ytterbium-based semiconductor, YbCuS2, with 4f13 configuration. My stay aimed to investigate the magnetic structure and crystalline electric field excitations of this Yb-zigzag chain compound. In this report, I record my experimental stay and a summary of the results obtained by these measurements.
