Spin-phonon coupling in AFM transition-metal mono-oxide
Time-of-flight INS measurements were performed on single crystal NiO with the Wide Angular Range Chopper Spectrometer (ARCS) at the Spallation Neutron Source. Experiments were performed on NiO single crystal mounted in an aluminum can and cooled using a closed-cycle helium refrigerator. Measurements were conducted at T = 100 K and 650 K, with the [HHL] scattering plane aligned horizontally. A Fermi chopper with slit spacing of 1.52mm, spinning at 300 Hz, was used to select an incident neutron energy of 100 meV. All datasets were normalized to a vanadium standard to correct for detector efficiency and solid angle coverage. The data sets include the .nxs files, the generated .hdf5 files (for use with Phonon Explorer), and Python scripts used to create them.
