Inelastic magnetic neutron scattering in CePd3
نویسندگان
چکیده
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 60meV is considerably weaker. These results are in qualitative accord with predictions of the Anderson lattice. The Q-dependence may resolve an older controversy concerning the low-temperature scattering. We discuss the relationship of these results to our recent results in YbAl3. r 2007 Elsevier B.V. All rights reserved. PACS: 75.20.Hr; 61.12.Ex; 71.28.+d

Q-dependence of the spin fluctuations in the intermediate valence compound CePd3.
We report inelastic neutron scattering experiments on a single crystal of the intermediate valence compound CePd3. At 300 K the magnetic scattering is quasielastic, with half-width Γ = 23 meV, and is independent of momentum transfer Q. At low temperature, the Q-averaged magnetic spectrum is inelastic, exhibiting a broad peak centered near Emax = 55 meV. These results, together with the temperat...

Neutron scattering is proved to be a vital probe in unveiling the magnetic properties of high temperature superconductors (HTSC). Detailed information about the energy and momentum dependence of the magnetic dynamics of HTSC have been obtained directly by this technique. Over the past decade by improving the crystal growth methods, large and high quality single crystals of HTSC, which are ess...

متن کاملMagnetic excitations in the low-temperature ferroelectric phase of multiferroic YMn2O5 using inelastic neutron scattering.
We studied magnetic excitations in a low-temperature ferroelectric phase of the multiferroic YMn(2)O(5) using inelastic neutron scattering (INS). We identify low-energy magnon modes and establish a correspondence between the magnon peaks observed by INS and electromagnon peaks observed in optical absorption [A. B. Sushkov et al., Phys. Rev. Lett. 98, 027202 (2007).]. Furthermore, we explain the...
