Crystal structure and superconducting properties of hexagonal lithium-niobium oxynitride.

A hexagonal oxynitride (Li(0.88)□(0.12))Nb(3.0)(O(0.13)N(0.87))(4) was synthesized through ammonia nitridation of LiNb(3)O(8). The structural analysis revealed that this oxynitride consists of alternate stacking of octahedral and prismatic layers with different Li/Nb ratios: significant amounts of Li and Nb atoms (Li/Nb = 43/57) coexist in the octahedral layer, while the prismatic site is prefe...

Synthesis and Crystal Structure of Cs3nb2br9, a Dinuclear Niobium Cluster

SYNTHESIS AND CRYSTAL STRUCTURE OF CS3NB2BR9, A DINUCLEAR NIOBIUM CLUSTER. The niobium bromide cluster compound, Cs3Nb2Br9, was obtained by solid-state synthesis techniques in reaction of stoichiometric amounts of CsBr, Nb powder and NbBr5. It crystallizes in the hexagonal system with unit cell parameters a = 7.7183(2) Å, c = 18.3396(7) Å, space group P63/mmc, Z = 2. Its crystal structure was d...

Frontiers of Ferroelectricity

Three kinds of near-field microscopy imaging mode including SEAM (Scanning electron acoustic microscopy), PFM (Piezoresponse force microscopy) and SPAM (Scanning probe acoustic microscopy) have been developed to investigate domain structures of ferroelectric ceramics, crystals and thin films in our studies. The domain imaging mechanisms are presented individually in three imaging modes. Sub-sur...
