High precision measurement of the spin waves in Yttrium Iron Garnet
Yttrium Iron Garnet (YIG) is a material with extremely wide ranging applications. It is a ferrimagnetic spinel with the narrowest ferromagnetic resonance linewidth of any known... -
Topological magnons in Cu2OSeO3
Recently, it was predicted topological nature of the magnetic excitations of Cu2OSeO3. It turned out that the system belongs to the class of topologically non-trivial magnets... -
High resolution measurement of mode Grueneisen parameters in the negative the...
ZrW2O8 is the classic example of a material exhibiting negative thermal expansion (NTE), i.e. lattice shrinkage on warming. The origin of this behaviour has been controversial... -
Examining the magnon-magnon/phonon coupling in a new multiferroictwo-dimensio...
Non-collinear two-dimensional triangular antiferromagnets (2D TLAF) are currently an area of much active research due to their unique magnetic properties which lead to... -
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... -
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...
