Finding new materials with antiferromagnetic (AFM) Kitaev interaction is an urgent issue to broaden and enrich the quantum magnetism research significantly. By carrying out inelastic neutron scattering experiments subsequent analysis, we conclude that Na$_3$Co$_2$SbO$_6$ Na$_2$Co$_2$TeO$_6$ are honeycomb cobalt-based AFM systems. The spin-orbit excitons at 20-28~meV in both compounds strongly s...

The crystal structure of the high-pressure polymorph meyerhofferite, ideally Ca 2 B 6 O (OH) 10 ·2(H O), has been determined by means single-crystal synchrotron X-ray diffraction data. Meyerhofferite undergoes a first-order isosymmetric phase transition to meyerhofferite-II, bracketed between 3.15 and 3.75 GPa, with large volume discontinuity. is marked an increase in coordination number boron ...

Abstract The structural properties of Ba 2 YNbO 6 were adjusted and compared with experimental data through an interatomic potential that was optimized here is based on a model known as the shell used in this work for oxygen ions. Intrinsic extrinsic defects calculated minimization crystal lattice energy computational modeling. Calculations showed rare earth ions prefer to incorporate Y 3+ site...
