  • The magnetic form factors of iron and nickel have been studied by means of coherent inelastic vibrational scattering of polarized neutrons in high-symmetry directions for momentum transfers which are different from the reciprocal-lattice vectors. The vibrational scattering has been separated from other inelastic scattering processes, such as spin-wave scattering, by means of energy analysis on a triple-axis polarized-neutron spectrometer. In the case of iron we see definite departures from the interpolated elastic form factor, depending on the direction and magnitude of the scattering vector. In the case of nickel the inelastic form factor is identical, within experimental error, to themore » elastic form factor.« less
  • Electrons, optical phonons, and acoustic phonons are often driven out of local equilibrium in electronic devices or during laser-material interaction processes. The need for a better understanding of such non-equilibrium transport processes has motivated the development of Raman spectroscopy as a local temperature sensor of optical phonons and intermediate frequency acoustic phonons, whereas Brillouin light scattering (BLS) has recently been explored as a temperature sensor of low-frequency acoustic phonons. Here, we report the measured BLS spectra of silicon at different temperatures. The origins of the observed temperature dependence of the BLS peak position, linewidth, and intensity are examined in ordermore » to evaluate their potential use as temperature sensors for acoustic phonons.« less
  • We have performed a study of magnons in Mo/Ni metallic superlattices with the use of Brillouin scattering. The magnetic field and modulation wavelength dependence of the magnon frequencies are found to be in reasonable agreement with theoretical predictions. Certain features in the spectra which are characteristic of a superlattice and cannot be expalined by a trivial superposition of the spectra of the individual constituent layers are presented and discussed.
  • Based on the [ital s]-[ital d] exchange model, we investigate the temperature-dependent resistivity arising from the scattering of electrons off fractons and magnons in dilute two-dimensional Heisenberg antiferromagnets. The result shows that the existence of fractons will lead to a linear temperature dependence of the resistivity over a wide temperature range and its slope [ital d][rho]/[ital dT] is nearly a constant, which is consistent with experimental results in high-[ital T][sub [ital c]] oxides, while the magnon scattering will contribute a resistivity varying as [ital T][sup 3/5] almost over the whole temperature region.
