Structural and magneto-transport properties of electrodeposited bismuth nanowires
Arrays of semimetallic Bi nanowires have been successfully fabricated by electrodeposition. Each nanowire consists of elongated Bi grains along the wire direction. Very large positive magnetoresistance of 300% at low temperatures and 70% at room temperature with quasilinear field dependence has been observed. These features are desirable for wide-range field sensing applications. © 1998 America...
متن کاملStructural and transport properties of Bi-substituted Co2MnO4
We report the structural and transport properties of the Bi-substituted Co2MnO4 multiferroic materials. Samples synthesized using the solid state reaction route with the composition BixCo2−xMnO4 0x 0.3 exhibit a single phase behavior with a cubic spinel structure space group Fd3m . The lattice parameter was found to increase with the Bi substitution. The dc-conductivity studies reveal that all ...

تعداد 20 رأس میش نژاد نائینی 6+-24 ماهه، با میانگین وزن 2/3-+40 کیلوگرم، همراه با 20 رأس بره های آنها در قالب طرح کاملا تصادفی اثر بتائین و مکمل سولفات بر خصوصیات شیر و پشم و عملکرد بره ها بررسی شد. میش ها بطور تصادفی در چهار تیمار قرار گرفتند. تیمارها عبارت بودند از: 1-گروه شاهد 2-بتائین (05/0 درصد ماده خشک) 3-سولفات (24/0 سولفور درصد ماده خشک 4-بتائین هرماه با سولفات. جیره غذائی طبق nrc با مح...
15 صفحه اولScanning Tunneling Spectroscopy of Lead - Substituted Bismuth Strontium Copper Oxide
The hole-doped cuprate Bi2-_Pb.Sr 2CulO 6+6 is doped with lead to the solubility limit of x = 0.38 and studied using STM/STS in the overdoped regime where T, < 2K. Despite the high lead content, residual supermodulations are observed in the BiO plane. In agreement with previous studies on (Pb,Bi)-2201, there is no separation of the sample into Pb-rich and Pb-poor domains, nor is there a spectra...
متن کاملElectrical transport properties of single bismuth nanowires
Due to its unique electronic properties bismuth is of enormous interest for studies on the nanoscale. In particular, when the object size is comparable to the mean free path of charge carriers le (~ 100 nm and ~ 400 μm at 300 and 4 K, respectively [1]), mesoscopic effects such as electron scattering at both surface [2] and grain boundaries [3] become significant. For investigating the influence...
