چکیده

Thermal conductivity of superconducting MgB 2 was studied in both the superconducting and the normal state region. The latter is almost equally determined by the electronic-and the lattice contribution to the total thermal conductivity. In the superconducting state, however, the lattice contribution is larger. The electronic thermal conductivity below T c was derived from the experimental data considering the Bardeen-Rickayzen-Tewordt theory together with the model of Geilikman. The analysis shows that electron scattering on static imperfections dominates.

1 Thermal conductivity of superconducting MgB

The thermal conductivity of superconducting MgB 2 was studied in both the superconducting and normal state region. The latter is almost equally determined by the electronic-and the lattice thermal conductivity. In the superconducting state, however, the lattice thermal conductivity is larger. The electronic thermal conductivity below T c was derived from the experimental data considering the Ba...

Transport Properties of Mgb 2

1. Introduction The discovery of the superconductivity in MgB 2 [1] at a temperature as high as 39 K has stimulated a enormous interest about the comprehension of its mechanism [2][3]. The study of the electron transport properties may give an insight into the normal state conduction process and into the electronic structure of MgB 2. From this point of view the results are contradictory. In fa...

Anisotropy parameters of superconducting

Data on macroscopic superconducting anisotropy of MgB 2 are reviewed. The data are described within a weak coupling two-gaps anisotropic s-wave model of super-conductivity. The calculated ratio of the upper critical fields γ H = H c2,ab /H c2,c increases with decreasing temperature in agreement with available data, whereas the calculated ratio of London penetration depths γ λ = λ c /λ ab decrea...

2 00 1 Detailed electronic structure studies on superconducting MgB 2 and related compounds

Our recent electronic structure studies on series of transition metal diborides indicated that the electron phonon coupling constant is much smaller in these materials than in superconducting intermetallics. However experimental studies recently show an exceptionally large superconducting transition temperature of 40 K in MgB 2. In order to understand the unexpected superconducting behavior of ...

Metallurgical phases and their magnetism at the interface of nanoscale MgB2/Fe layered structures.

We report on the characterization of metallurgical phases and their magnetism at the interfaces of nanoscale MgB(2)/Fe layered structures. MgB(2)/(57)Fe multilayers with varying layer thicknesses were prepared by vacuum deposition and investigated, before and after annealing by electrical resistance measurements, x-ray diffraction and (57)Fe conversion-electron Mössbauer spectroscopy (CEMS) dow...
