Superconductivity induced by Ni doping in BaFe2As2 single crystals
A series of 122 phase BaFe2−xNixAs2 (x = 0, 0.055, 0.096, 0.18 and 0.23) single crystals was grown by the self-flux method and a dome-like Ni doping dependence of the superconducting transition temperature was discovered. The transition temperature T on c reaches a maximum of 20.5K at x = 0.096, and it drops to below 4K as x > 0.23. The negative thermopower in the normal state indicates that th...
متن کاملSuperconductivity at 22 K in Co-doped BaFe2As2 crystals.
Here we report bulk superconductivity in BaFe1.8Co0.2As2 single crystals below Tc=22 K, as demonstrated by resistivity, magnetic susceptibility, and specific heat data. Hall data indicate that the dominant carriers are electrons, as expected from simple chemical reasoning. This is the first example of superconductivity induced by electron doping in this family of materials. In contrast with cup...
متن کاملImproving Newsgroup Clustering by Filtering Author-Specific Words
Introduction. This paper describes the first step in a project for topic identification in help-desk applications. In this step, we apply a clustering mechanism to identify the topics of newsgroup discussions. We have used newsgroup discussions as our testbed, as they provide a good approximation to our target application, while obviating the need for manual tagging of topics. We have found tha...
متن کاملUniformity and homogeneity-based hierarchical clustering
This paper presents a clustering algorithm for dot patterns in n-dimensional space. The n-dimensional space often represents a multivariate (nf -dimensional) function in a ns-dimensional space (ns + nf = n). The proposed algorithm decomposes the clustering problem into the two lower dimensional problems. Clustering in nf -dimensional space is performed to detect the sets of dots in n-dimensiona...
متن کاملPossible Sign-Reversing s-Wave Superconductivity in Co-Doped BaFe2As2 Proved by Thermal Transport Measurements
Thermal transport measurements have been performed on single-crystalline Co-doped BaFe2As2 down to 0.1 K and under magnetic fields up to 7 T. Significant peak anomalies are observed in both thermal conductivity and thermal Hall conductivity below Tc as an indication of the enhancement of the quasiparticle mean-free path. Moreover, we find a sizable residual T -linear term in thermal conductivit...
