The origin of ultra-low thermal conductivity in the thermal barrier material ...
Thermal barrier materials are used in modern turbines to enable them to run above the melting temperature of the turbine blades. However, to go to higher temperatures (and... -
Exotic spin excitations in a quasi one-dimensional anisotropic Heisenberg magnet
Very recently, string states have been identified for the first time in antiferromagnetic Heisenberg-Ising chain SrCo2V2O8 in longitudinal magnetic fields using high-resolution... -
Magnon dispersion in the polar ferrimagnet BaCaFe4O7
Polar or non-centrosymmetric ferri(-o)magnets offer a plethora of potential technological devices;the inherent magnetoelectric effect can underpin both pyroelectric or... -
Transverse field evolution of magnetic excitation spectrum in Nb1-yFe2+y
Our previous neutron scattering on C14 Laves phase compounds Nb1-yFe2+y revealed that a spin-density-wave (SDW) is masking an underlying ferromagnetic (FM) quantum critical...
