Inelastic neutron scattering study on new Mott-insulating oxychalcogenides, L...
La2O2M2OSe2 (M=Fe, Co, Mn) are layered Mott-insulating antiferromagnets with a potential to be a non-copper high-Tc superconductor. All compounds have shown unusual magnetic... -
Phonon Density of States in Nanocrystalline YAG:Cr
Here we propose to measure the phonon density of states in nanocrystalline samples of YAG:Cr. Our parallel luminscence measurements have revealed dramatic changes in the phonon... -
INS on a 2D quantum spin liquid candidate material without structural disorder.
The ordered double perovskite Sr2CuWO6 is a quasi-two dimensional J1/J2 frustrated square lattice model antiferromagnet. The divalent Cu carries S = 1/2 while the W (VI) is 4d0....
