Magnetic fluctuations in the possible spin-triplet superconductor LiFeAs
LiFeAs is one of the newly discovered FeAs superconductors with still large T_c of 18K. First inelastic neutron scattering experiments on powder and on single-crystalline... -
Hourglass dispersion in overdoped manganites
Overdoped manganites were recently shown to exhibit stripe-like ordering of charges orbitals and magnetic moments. The magnetic excitations in these materials show close...
