Ab Initio Study of Half-Metallic Feature and Electronic Structure of A2FeMoO6 (A=Ba,Ca) Magnetic System
Electronic structure Half metallic Complex Perovskite
2010/9/29
We report several ab initio calculations performed over the A2FeMoO6 (A=Ba, Ca) double perovskite. Results show that it is an insulator for the spin up orientation and conductor for the other one. We ...
Reconstructing the history of fluid flow at cold seep sites from Ba/Ca ratios in vesicomyid clam shells
history of fluid flow cold seep sites Ba/Ca ratios vesicomyid clam shells

Hydrogen sulfide discharge at cold seep sites is recorded as enrichment in the barium to calcium (Ba/Ca) ratio in shells of vesicomyid clams collected live from cold seeps in Monterey Canyon and the C...
双Tl-O层Tl-Ba-Ca-Cu氧化物超导体的能带结构
能带结构 Tl-Ba-Ca-Cu-O 超导体
2010/2/21
利用EHT近似下的紧束缚能带结构计算方法计算了Tl-Ba-Ca-Cu氧化物超导体双Tl-O层体系的能带结构。计算结果表明费米面在a~*b~*面上是封闭的, 费米能级上电子态密度的增加和体系转变湿度(T_c)的提高是相一致的。Cu-O面上Cu和O的净电荷有规律的变化说明, Cu-O面上Cu和O的离子价态可影响该体系的超导电性。
