Study of low-energy magnetic excitations in single-crystalline CeIn3 by inelastic neutron scattering
Inelastic neutron scattering experiments were performed on single crystals of the heavy-fermion compound CeIn3 for temperatures below and above the Néel temperature, TN . In the antiferromagnetically ordered phase, well-defined spinwave excitations with a bandwidth of 2 meV are observed. The spin waves coexist with quasielastic (QE) Kondo-type spin-fluctuations and broadened crystal-field (CF) ...

متن کاملInelastic X-ray Scattering by Electronic Excitations under High Pressure
Investigating electronic structure and excitations under extreme conditions gives access to a rich variety of phenomena. High pressure typically induces behavior such as magnetic collapse and the insulator-metal transition in 3d transition metals compounds, valence fluctuations or Kondo-like characteristics in f -electron systems, and coordination and bonding changes in molecular solids and gla...
متن کاملIntensities of surface spin wave excitations in inelastic electron scattering
The intensity of surface spin wave excitations in inelastic electron scattering is measured as function of electron energy for fcc and hexagonal close packed (hcp) cobalt layers. Intensities are converted into scattering probabilities with the help of a recently established calibration of our spectrometer. The scattering probability as function of energy exhibits a peak around 7 and 3 eV for fc...
متن کاملUltra-High Resolution Inelastic Neutron Scattering
Two types of ultra high energy resolution neutron scattering instruments, the backscattering spectrometer and the spin echo spectrometer, are described. Examples of the types of research which can be done with these instruments are given and plans for a cold neutron backscattering spectrometer which will be built in the NIST Cold Neutron Research Facility (CNRF) are discussed. It is hoped that ...
