• 論文の詳細を見る

• Neutron inelastic scattering stttdy has been perforzned on aligned single crystals of quasi-two-dimensional spin-gap systern Cab,too. By analyzizag the dispersion ctrrves and the strttcturefactor of the triplet excitation, a physical picture of'the present spin systena has been constructed:The plaqtrette singlet units of four S : 172 V-atoms within four "corner-linked" V05 pyramidsform the two-ditnensional linkage of the spins by the interactions between the V-spins within the"edge-linked" V05 pyramids. We have remeasured the NIVIR relaxation rates and obtained thespin-gap behavior consistent with the neutron results.
