Abstract

High energy magnetic excitations in the Kondo compound with the ε-TiNiSi type crystal structure, CeRhSb, were observed by inelastic neutron scattering. The magnetic excitation spectrum at 17 K shows a broad inelastic peak which is well reproduced by the Lorentzian spectral function centred at E₀=32±4 meV with a half width of Γ∼E₀.

The muon spin rotation/relaxation/resonance (μSR) spectroscopy has become an important tool for probing local static and dynamic magnetic properties. In over two decades a quite substantial body of μSR data has been collected from rare-earth and actinide materials, the latter, however, mostly restricted to samples containing uranium. μSR is the measurement of the temporal development of the spatial orientation of the spins of muons, which have been implanted in the material of interest with all spins initially fixed in one direction (complete muon spin polarization). μSR can be performed either with positive or negative muons. The latter behave like heavy electrons and will be captured into Bohr orbits by the atoms in the sample material. They will quickly reach the ls ground state, whose orbital radius, however, is comparable to nuclear radii. Negative muons thus sense predominantly the effects of the protonic charge distribution and the result is primarily of interest to nuclear physics. The magnetic field at the site of the muon in a magnetic compound is, at least in part, created by the dipole moments on neighboring paramagnetic atoms or ions.
