Are magnetic excitations in the Yb based pyrochlores really gapless?
A recent neutron study of a powder sample attests a splayed ferromagnetic structure for Yb2Ti2O7. However in the same work the authors report gapless magnetic excitations even... -
Quasi-elastic neutron study of the organic cation dynamics in the halide pero...
Solar cells based on a layer of halide perovskite have recently seen rapid increases in efficiency, with certified values in excess of 20%. The prototypical material of this...
