Spin-wave lifetimes throughout the Brillouin zone.
We used a neutron spin-echo method with microelectron-volt resolution to determine the lifetimes of spin waves in the prototypical antiferromagnet MnF2 over the entire Brillouin zone. A theory based on the interaction of spin waves (magnons) with longitudinal spin fluctuations provides an excellent, parameter-free description of the data, except at the lowest momenta and temperatures. This is s...
متن کاملSoftening and Broadening of the Zone Boundary Magnons in Pr0.63Sr0.37MnO3
We have studied the spin dynamics in Pr0.63Sr0.37MnO3 above and below the Curie temperature TC = 301 K. Three distinct new features have been observed: a softening of the magnon dispersion at the zone boundary for T < TC , significant broadening of the zone boundarymagnons as T → TC , and no evidence for residual spin-wave like excitations just above TC . The results are inconsistent with doubl...
متن کاملNominal Hazard Zone in Medical Laser Centers
Control the laser beam hazards for class IIIB and IV laser is concluded: engineering and executive controls. In executive control, when laser beam enters to the free space, the controlled area must be identified to protect people and control the radiation exposure limits. Given the fact that the laser light of the laser is entering the environment, the identification of the area under control i...
متن کاملNumerical Treatment of short Laser Pulse Compression in transient stimulated Brillouin Scattering
Received: 10.04.2002 Accepted: 24.04.2002 Abstract Results of numerical investigation of the compression process of short pulses during essentially nonstationary SBS are presented, taking into account the diffraction and focusing of the interacting light beams and the finite oscillation period and lifetime of hypersound waves in nonlinear media.
متن کاملExtrapolative approaches to Brillouin-zone integration
A highly efficient extrapolative Brillouin-zone integration scheme is presented that requires a very low k-point sampling density for spectral integrations. It is important to use an extrapolative approach, since at low sampling densities interpolative schemes are hindered by problems associated with band crossing, which introduce spurious singularities in the density of states ~DOS!. The infor...
