Inelastic neutron scattering peak in Zn substituted YBa2Cu3O7

Inelastic magnetic neutron scattering in CePd3

We have performed time-of-flight neutron scattering measurements on a single crystal of the intermediate valence compound CePd3. At 10K, a Kondo-esque inelastic magnetic scattering peak occurs near DE 1⁄4 60meV with maximum intensity for momentum transfer Q near the ð 2 ; 1 2 ; 0Þ zone boundary. Spectral weight is transferred to lower energy as Q varies until at zone center the intensity at 60m...

Phonon and magnetic neutron scattering at 41 meV in YBa2Cu3O7.

We report inelastic neutron scattering measurements at excitation energies h̄v , 41 meV in YBa 2Cu 3O 7. We separate magnetic and phonon contributions to the scattering cross section by a detailed analysis of the momentum dependence of the scattered intensity. The previously reported broad peak around q ­ spya, pyad in the normal state can be entirely accounted for by a phonon which primarily in...

Soil Carbon Measurements Using Inelastic Neutron Scattering

Soil carbon sequestration is a whole new area of energy related research that provides a fundamentally new approach for dealing with climate change resulting from the substantial increase in CO2 concentration in the atmosphere. Carbon sequestration in soil is recognized to play a major role in allowing fossil fuels to remain a vital component of the national energy mix. At present soil carbon i...

Inelastic Neutron Scattering Study of Mn12-Acetate

We report zero-field inelastic neutron scattering experiments on a deuterated powder sample of Mn12-Acetate consisting of a large number of nominally identical spin-10 magnetic clusters. Our resolution enables us to see a series of peaks corresponding to transitions between the anisotropy levels within the spin-10 manifold. A fit to the spin Hamiltonian H = −DS z − μBB · g · S −
