Spin excitations in the superconducting FeTe0.6Se0.4
The FeTe1-xSex series exhibits superconductivity over a broad range of doping. Previously we have made extensive neutron scattering measurements on superconducting x = 0.49 and... -
Magnetic Excitations in Chromium
Chromium is unique amongst the d-band elemental metals in that it has a spin density wave ground state. The spin density wave is caused by Fermi surface nesting between electron... -
Magnetic excitation in triangular latticce antiferromagnet alpha-CaCr2O4
The triangular Heisenberg antiferromagnet is the classic example of the frustrated magnet, here the ground state forms a non-collinear 120° structure. A number of different...
